I enjoy playing as Bayonetta more than I enjoy playing as Ryu, but I dislike Bayonetta's design. It's kind of a toss-up.
I suppose I'll give the vote to Bayonetta. Kinda weird though, considering I enjoy Street Fighter and am able to pull off the moves. Just not crazy about Ryu in Smash Bros.
Bayo by far, I still haven't bought Ryu because I just don't care about him or his stage. (Actually he's the only DLC character I haven't bought.) Bayonetta is a cool character and her stage is amazing.
Bayonetta, hands down. I watched some replays from the first day of downloading last week and my Bay play was atrocious versus replays from a few days later after I figured her out. So mean to down smash friends off that ledge.
Ryu is so slow and feels really clunky to play with... I never played street fighter before but his being put into smash I thought was epic, then I played with him and it was like.... meh....
same thing with bayonetta, never played her games, but thought it was cool she got added... I played with her and it was super fun to slide around, do combos and her play style is unlike any other, but in the best way!
