You will get answers, but frankly you're just better off learning the motion inputs, because every major "proper" fighter uses them, from Street Fighter to Guilty Gear. Hell
You learn them once, and this skill is with you forever. You will be able to play anything Capcom / SNK / ArcSys and tons of other games. Even Tekken needs DP/QCF for things like wave dashing.
Yes, I do get that you may not have time for this crap, but in general if you don't want to learn anything, fighters probably aren't for you, period. Fighters aren't really about single player content, they're about skill and knowledge.
Keep in mind that in general for execution, the controllers rank about this way:
Arcade stick > keyboard > GOOD dpads >>> bad dpads (see X360) >>>>> analog
Also keep in mind that the newer the game, the more leniency it has when it comes to controls. And in general fighters like SF or KoF have some leniency mechanics like negative edge or button hold. Finally, every fighter will have "easy" and "hard" characters when it comes execution, it absolutely doesn't mean they're necessarily stronger.
