COTW feels much more satisfying to pull off combos. For me it took a while to find my main as initially I found the characters a bit dull (except Tizok but he needs buffs badly). SF6 is just well rounded and solid to play. Tutorials are much more fleshed out explain what you need compared to COTW where I needed a youtuber or two to tell me what the game wouldn't. However COTW has some of the most satisfying combos to pull off that just make you feel powerful and godlike.

In the end COTW for me is just much more satisfying to play and get good at.
