Anime Southern Supreme Kai VS SSJ3 Goku (in his Other World body)
SS Kai hasn't really been seen enough to give us a full idea of his abilities. We know that he held his own against Kid Buu to the point where Buu instinctively absorbed him, but all we actually saw was three seconds of their battle. We know that Goku can at least hold his own with Kid Buu too, so by feats he should win, although it's not impossible for SS Kai to actually be stronger than him.
Post-ROSAT SSJ Goten VS Dabura (no spitting)
Goten and Trunks are Full-Power Super Saiyans, the same as Goku and Gohan in the Cell Games, and we know that neither of them stood a chance against Cell when he was at full power. Goten did provide a challenging sparring partner for Adult Gohan, but considering Adult Gohan was even weaker than as a kid, the gap between Goten and Kid Gohan is quite large, meaning the gap between Goten and Cell is even larger. I don't think that their limited amount of time in the ROSAT was nearly enough to bring him on Cell's level, and Dabura is at least just as strong as Cell.
Recoome VS Dore (no Ki attacks, flying, or armor for both)
Dore stomps. Reccoom got oneshotted by pre-Zenkai Goku holding back, Dore caught post-Freeza Goku's kick and briefly put him in a submission hold.
Cyborg Tao VS Vegeta (Saiyan Saga, weakened and crawling towards his space pod)
I have to imagine that damn near anyone could have beaten Vegeta at that point. When it's said that Saiyans need to be near death for a Zenkai to occur, people often underestimate just what near death really means.
Eastern Supreme Kai (no paralysis/materialization magic) VS SSJ Bardock (Episode of Bardock) dressed up in Goku's bloodstained clothes, with a permanent "M" Majin tatoo on his forehead, makeup to darken the edges of his eyes, and professionally drawn on bulging veins all over his body, a voice-alteration necklace that makes him sound extra demonic, file-sharpened teeth, and his clothing will be made of fabric that creates visible static with every move
ES Kai takes the biggest shit, before realizing his opponent is substantially weaker than the guy he claimed he could kill with one blow. ES Kai firmly stomps from there.
