They can offer different things. I have a ps4 and a gaming pc. Personally I like to sit on my couch and use the tv. Although I have wireless periphials for the computer to do that, most of the time the ps4 just suits that experience better. I'll often just use the pc for games I can't play on the PS4. And because I'm sitting 8 feet away from my screen, graphically it's not like you're losing a ton with a console either.
