Garou and Kanoh are basically the same character. Both can copy any martial arts technique by seeing it performed once, adapt to fighting styles, and come up with basically new styles on the drop of a dime.
In terms of skill Agito blows Garou out of the water and his skill adaptation is also better, but Garou's sheer strength development is better than Kanoh's by a longshot. It just depends on if Kanoh can one shot with Dragon Shot, which in Omega he basically spams with every blow, before Garou can grow too strong and one-shot in turn.
Garou copying Pre-Initiative or Formless is never happening if even the Fist Eye couldn't comprehend it let alone analyze it, not to mention Formless is basically Magic as well, so in terms of the "weirdness" of their skills it's basically the same. Formless literally lets you transform into water.
I think I'm going incon. They're both pretty similar characters and both have ways to take the other out for the count that could go either way.
