Depends, when it comes to games with high execution like MVC3 it is needed. Since in MVC3 the attacks don't come out until you finally push the desired button. Plus the fact that some stuff like the ROM infinite is far easier (to some extents) on a stick. As for MK, they are not needed since the game has dial-a-combos. You can execute combos as long as you press the right combination no matter what.
Lolwut? MvC3 is high execution? Have you seen pad players playing MvC3? It's amazing. IGT is a well known pad player and he's pretty good.
Besides, SFIV is much more execution heavy, and Wolfkrone plays probably the most execution heavy character, C. Viper, in the game on pad.
What the hell is this about pressing buttons and attacks coming out or not? Of course it comes out. You press the button, something happens. Same with Pad or Stick.
You don't know squat about Arcade Sticks and Pad and execution.
It's all about preference.
