Classic when playing against others. Modern for World Tour and trying out a character in Arcade mode. Starting out, it's fun to see an auto-combo and then bring it over to classic.

Don't really mind going up against any control type/character. What controller, execution, and reaction times already varies across all players. I'm having more fun when people are making decisions and executing what they want to.

I use Modern.

I haven’t played a street fighter game since 3 alpha, and have spent more time playing smash bros than anything else, making Classic a difficult change. I very much enjoy the neutral game more than memorizing combos, so the auto-combos are nice too.

I really wish I could choose the layout of the abilities, though. Some use the same button but with a different delay or hold, and I wish I could just do both.
