By official numbers:Whatever you want,nothing makes sense anyway.
By the gaps implied at early DB:Tien stated he was surprised that Goku had increased his strength,
meaning Weighted Goku>Goku(post holy water).Nothing indicates it was an enormous increase,
though.I think Weighted Goku is like 1.5x stronger than 3 years before.
Popo,on the other hand,effortlessly ragdolled Kid Goku,meaning he had 2x or more an advantage.
Popo wins.
