Once you go PC, it's hard to go back.
Modding games can be a beautiful and hilarious experience, and it's one of the main reasons to love PC.
Is your gaming PC falling behind in performance? No problem, if you have a decent processor then you can just throw in a new GPU and max out games yet again. For example, my computer has a processor from 2008/2009, and it still keeps up with all but the most extreme graphics cards before it becomes a bottleneck.
Owning a PC is like also owning a PS2, Xbox, Dreamcast, Gamecube, Wii, etc. because you can emulate games from those console.
Settings are tweakable. If you want to sacrifice some visual effects for better framerates, you can. But you won't have to sacrifice too much, because after you factor in the money you'll save through steam sales and not having to pay for online, you can spend the same on a $800+ PC and games as you would with a 400 console and games+online. And that $800 PC will have roughly 2-3 times the power of a console.
Sure, consoles are easy to use, but it's not like PCs are rocket science. Build it (aka play adult legos), install the operating system (incredibly easy) and update the graphics drivers (literally just opening an application and clicking the "download latest drivers button" and everything will run fine, unless you're messing with files.
