The major factor the OP neglects: most people these days who aren't going to get a dedicated gaming rig will get a laptop or a tablet, which are just about useless for high power gaming. About 2010 a PC tower became a specialized piece of equipment, and by and large a tower is what you need for gaming.
Some people will need to get one, anyway, but certainly not all.
Price-wise, I think PC and consoles are essentially identical. Console games are more expensive, while PC is largely hardware-oriented (but don't forget the time spent installing hardware or tweaking settings). PC gaming definitely offers the higher end experience, but it also comes at a price; glitches, settings not optimized for your hardware, etc.
Personally, I prefer consoles.
