This is the stupidest argument I've ever heard of. I mean, if one were intended to be better than the other, then why are we able to play Call of Duty on a PC and perform a Google search on Xbox?
PC people, you need to respect the fact that not everyone is as dextrous as you are. If you haven't noticed, controllers are much smaller than a keyboard, and at any given time, all the buttons on a controller will be used for something. Keybinds aren't as complicated to set when each button is guaranteed to have a purpose.
Console people, you need to respect the fact that some people just flat-out don't like consoles, for various reasons, though the main one I see is that people have used PCs most of their life, and don't feel comfortable with consoles. Old habits die hard.
Both of you, stop arguing. There are much better uses for your time and energy than arguing over this.
