I'm not trying to determine what factors go into a person's purchasing decision, or saying that people should only care about the games. What I'm saying is: IF you only care about performance, THEN you should buy a PC because you'll be able to get the best performance on PC. If you can't afford a PC, still don't buy a console, because if you only care about performance spending that $400 on a console isn't worth it... continue to save and get a PC in a couple months instead.
You're looking at it in a painfully black and white sense. It's not "I only care about performance" so saying "Just get a PC" isn't valid.
It's not "I only care about games" so "Choose based on those for PS4 and Xbox One."
So there is no correct answer for what is universally right - stop trying to state it as if there is.
