Yeah he was a little too strong and fast for SS Goku, I believe. His lead over Goku is probably similar to Cell’s lead over CG Goku. It seemed like weighted Kamiccolo would’ve easily beaten him.
From what I recall, #13 was superior, but not by much. The difference between the two seemed pretty minimal. He's probably weaker than Gingertown Cell.
Yeah, I'm not seeing much of a difference between SS Goku and Base 13 from the YT clips I just looked at. If they're just their Android arc selves then SS Vegeta >~ SS Goku ~ Base 13.
