, may have lost.M8
Despite being stronger than the Z Senshi in just his ordinary SSJ form, Broly lost because...
- As a result of absorbing the power of three other Saiyans, Goku just barely tapped into some degree of God Ki/SSJG(isn't that just convenient???). Unfortunately, by having a much less conditioned body & only three pure hearts as Vegeta wasn't quite "pure" by that point, Goku had to end it as quickly as possible since it would wear off in less than a minute, and his body could only hold it for one attack thus the "Toei punch".
- The power of three Saiyans & one Namek infused some of their greatest potential into Goku; Ultimate Gohan, Super Trunks, Rageta, and Super Namek Piccolo(isn't that even more convenient???) thus Goku managed to summon up a plethora of potential powers to pwn Broly. It was temporary though since it was borrowed energy.
- Broly's fluctuating Ki was causing his body to become unstable in various parts of his body, mostly in the center of his mass, and Goku's punch into Broly's stomach just happened to strike him the weakest point of integrity on his body causing a pressurized burst of Ki to explode from within Broly.
- Broly developed Delayed Onset Ki Disorder form as a result of constantly building up Ki, and stressing his body to its limit.
- Seeing Goku seethe with rage & power brought back traumatic memories in Broly, and he briefly dropped his power long enough for Goku to take advantage of.
- Broly simply became insane from being in LSSJ for so long, and lost control of his power completely.

Broly was still stronger than everyone as a SSJ, but still lost because...
- The God Ki that Goku possibly obtained had a negative effect on Broly's body & power, and made him overall weaker.
- Broly had lost an immense amount of power from when Goku pierced his belly, and his body only healed the injury instead of restoring his power completely.
- Broly still had Delayed Onset Ki Disorder from the previous battle, and stopped him from being able to fuel his attack against the Family Kamehameha.
- Seeing Goku again may have brought back another traumatic episode for Broly, and he dropped his power yet again.
- Broly became insane again, and just forgot how to use his Ki properly.

Even though he was imperfectly cloned, Broly still had the advantage until...
- The cloning process may have simply had its limitations in how long Broly could hold his full power.
- The clone of Broly may have developed Onset Ki Disorder.
- The negative effects that the God KI had may have been with Broly on a genetic level.
- Any instance of Broly is just insane as usual.
- Apparently, Broly was also cloned together with the Wicked Witch of the East.
Not a compelling list of reasons, but I bet Koyama approves of at least one of these...or all of them.
