All of these quotes are from Herms' strength checker. The bolded portions are mine. It's pretty obvious that Goku is weaker than both Gotenks and Gohan.
For Gohan:
Note that these two are from before his powerup from the Old Kaioshin is even finished.
Chapter: 488 (DBZ 294), P4.3
Context: after Gohan gets mad and unintentionally releases his power
Gohan: “Wh-what the…!? Is-is this seething power…mine…!?”
Chapter: 488 (DBZ 294), P4.9, P5.1-2
Context: after Gohan’s unintentional display of power
Goku: “…Am…amazin’…So he really wasn’t just some regular dirty old geezer?...*talking to Kaioshin* ‘Do-dormant ability’…That’s a person’s true power, that they have hidden all along…Right?”
Kaioshin: “Ye-yeah…I-I think so…”
Goku: “Mu-must be…Man, Go-Gohan…Just how the heck much power is he hidin'?...”
These are from afterwards
Chapter: 496 (DBZ 302), P4.1-2
Gohan: “Ho-how can I turn into this mightiest of warriors!?”
Elder Kaioshin: “You transform into that Super whatever-it-is a lot, right? You’ll be fine if you just get the gist of that, and throw in a kiai.”
Gohan: “The gist of Super Saiyan…I-I got it…!”
Chapter: 496 (DBZ 302), P7.2-3
Context: after Gohan transforms into the ‘mightiest of warriors’
Goku: “It re-really is incredible…It’s super-duper…! Absolutely unbelievable…Your appearance has hardly changed…And you ain’t even a Super Saiyan…Yet you’ve been taken to su-such an extreme…”
Elder Kaioshin: “Hmph, transforming isn’t good. That Super whatever-its-called is the wrong way [of doing things]…”
Chapter: 497 (DBZ 303), P1.5
Context: as Gohan approaches Boo and co.
Piccolo: “It’s a str-strong ki…! I can’t tell who it is…Is it some new enemy…!?”
Note that Piccolo has felt Super Saiyan 3 before, so at the very least, Gohan is stronger than the SSJ3 Goku that fought against Fat Buu.
Chapter: 498 (DBZ 304), P2.3-4
Boo: “Far, far, waa~~aay far away, I felt a strong power…I won’t allow anyone to have a power stronger than mine…”
Super Buu remembers his time as Fat Buu, and has also felt SSJ3 Goku's power. So he is also stronger than SSJ3 Goku was against Fat Buu.
Chapter: 501 (DBZ 307), P5.5
Context: Elder Kaioshin warning Goku about recklessly going to rescue Gohan from Gotenks-absorbed Boo
Elder Kaioshin: “I hate to say it, but I don’t think you could win against this current Majin Boo even if the two of you went at him together…”
If Goku was stronger than Super Buu, then shouldn't he and Gohan (who was also stronger than Super Buu) have been able to manage something? You treat Buu's fusions as additive, so if Goku was stronger than Gohan, who was a good deal stronger than Super Buu, who was roughly even to SSJ3 Gotenks, then he should have been at least able to put up a fight against Buutenks. Instead, he opts for a PERMANENT FUSION WITH HIS SON.
Chapter: 502 (DBZ 308), P10.4-5
Context: after Gotenks-absorbed Boo's time limit runs out and Gotenks inside him turns back into Goten and Trunks
Goku: “Your power’s fallen a whole lot. Cheh…I’m a little disappointed. This way, Gohan will be able to beat you even on his own…”
Note, he says Gohan, not himself.
Now for Gotenks:
Chapter: 472 (DBZ 278), P9.4
Context: after explaining that Fusion lasts 30 minutes
Goku: “With these two, if they just manage to perform Fusion successfully, I think they’ll definitely be able to defeat [Boo] within 30 minutes. Fusion is just that extreme.”
Chapter: 489 (DBZ 295), P3.5
Context: Trunks doesn’t like the idea of fighting Boo as a Super Saiyan 3 from the start
Trunks: “I think…that we’ve already progressed so much that even in a regular state Fusion, we’ll be about equal with Majin Boo...”
They don't know about Super Buu's strength yet, but he believes that Gotenks has surpassed Fat Buu in base.
hapter: 489 (DBZ 295), P11.5
Context: seeing Gotenks after he’d trained in the Room of Spirit and Time
Piccolo: “He-he really is different…! He really has greatly powered up…! Th-this just might…!”
Still referring to his base form, indicating that in base he's on the same level as Fat Buu.
Chapter: 490 (DBZ 296), P12.7
Context: after Gotenks fights Boo a bit, and head-butts him
Piccolo: “He…he just might…possibly be able to de-defeat him…!”
Chapter: 491 (DBZ 297), P3.1
Context: as the Super Ghost Kamikaze Attack seems to finish Boo off
Piccolo: “It’s an inc…incredible fight, but something about it is really stupid…!”
Chapter: 492 (DBZ 298), P3.9
Piccolo: “You did well, you truly did well! Quite frankly I didn’t think you’d be able to do so much.”
Even in SSJ1, he's still managing to put up a fight against Super Buu. Not beat him, but he's not getting pulverized either.
Chapter: 493 (DBZ 299), P12.2-4
Kaioshin: “In-incredible…S-so this is Fusion?...”
Goku: “N-no…That’s Fusion, no doubt about it, but…Thi-this is Super Saiyan 3…! Un-unbelievable…Those rotten little brats…They al-already became Super Saiyan 3, and that took me years to finally manage it…Am-amazin’…haha…amazin’…!”
Note: So it seems that Goku never planned on Gotenks reaching Super Saiyan 3, but still thought he’d be able to defeat Boo (or at least that it was worth a shot).
Chapter: 495 (DBZ 301), P6.1-3, P7.1-3
Context: after Gotenks blasts Boo with the Rapid-Fire Die-Die Missiles and Piccolo stops him
Gotenks: “Well, whatever. I already did quite a lot, after all. He should be pretty weakened.”
*Boo comes out*
Gotenks: “…He ain’t weakened…This really pisses me off!”
Piccolo: “N-no…He is weakened…I don’t know about physically, but he’s weakened a little mentally…! Th-this is the first time…that he’s fought someone strong like you…He’s feeling flustered by someone whose strength is at least on par with his own…”
Gotenks: “Dehhehheh! So in other words, Majin Boo’s freaked out, huh!? That’s right! My strength ain’t half-assed! I’m the best in the universe!”
Piccolo: “Don’t let your guard down! He’ll be coming at you frantically now…!”
Gotenks: “Dahhahhah, that’s no problem, no problem at all! That’s just what I was hoping for!”
"At least on par with his own." Indicating that SSJ3 Gotenks is at least on Super Buu's level, and may in fact be stronger. This is the same Super Buu that Goku said would kill him and Vegeta.
Now for Goku
Chapter: 501 (DBZ 307), P5.5
Context: Elder Kaioshin warning Goku about recklessly going to rescue Gohan from Gotenks-absorbed Boo
Elder Kaioshin: “I hate to say it, but I don’t think you could win against this current Majin Boo even if the two of you went at him together…”
Chapter: 506 (DBZ 312), P8.1
Context: Goku points out that if he and Vegeta aren’t merged, Vegeta will have to return to the afterlife
Vegeta: “Hmph…That’s better than being merged with you…Anyway, there shouldn’t be any need for us to merge anymore, right?”
Goku: “We can’t know that! There’s [no] guarantee that we’ll be able to successfully rescue everyone who got absorbed from here and return Boo to the very first one of all…!”
Note: when Goku finds the good Boo later, he calls him “the very first one of all”, so apparently that’s the form of Boo he means here too.
Goku is still saying that they'll be needing fusion against Super Buu.
Chapter: 506 (DBZ 312), P12.4-5
Context: after Goku and Vegeta revert Boo back to regular evil Boo
Goku: “Hehhe~~eh! With this, Boo’s power should have fallen significantly! We’re almost there! See, see: the size of his ki is completely different than before!”
Vegeta: “Alright! Let’s blast out of here and escape!”
Goku: “Wait! Even though Boo has returned to normal a whole lot, we’re still simply no match for his strength! If we go outside like this, we’ll definitely be done in…!”
Yeah. And here is this. This quote by itself should have ended this debate a long time ago, but you continue to try to explain it away, or just ignore it.
Chapter: 506 (DBZ 312), P13.1
Context: still talking about how they’re no match for Boo
Goku: “…But there is one way we can win!”
Vegeta: “You want to say Fusion, right? Well who cares about that?!”
Goku: “Huh? You know about it?”
Vegeta: “I saw it from the afterlife…You’ve got to be joking! You think I’d perform those ugly poses…?! Anyway, I thought I told you that I’m not going to merge with you a second time.”
"One way we could win. Yep.
Note that all three knew how strong Super Buu was. Gotenks and Gohan fought him. Goku said that he'd be killed. Goku was trying to get Vegeta to fuse with him. The same Goku who is nearly obsessed with having fair, one-on-one fights. You keep bashing other peoples' reading and literary skills, but maybe you should take a step back and work on your own?
