Both are great

I play PC

PC for fps and mmos. Console for Single player RPGs or action games like Tomb Raider, Drake etc.

a pc can be much better , but is more expensive..
playstation have so many good exlusive title
you need both

Pros for console:
The simplicity.
AAA game priority.

Pros for PC:
Mods. A single popular game will never end if you're willing to mod it.
Control options. On PC, you have a keyboard and mouse, right? The keyboard is a fantastic multi-purpose tool, and a mouse has accuracy and precision that a joystick can't match, particularly in first person shooters.

I have PS4 and play on it if there is a title that was not released on PC and I really want to play it.
But most of the time it sits and do nothing.

PC is just so much better. Games are cheaper and you don't need to pay for multiplayer. But the last one is not very important for me, because I play single player only with on exception for FIFA.

I own both ps4 and PC, but usually when I play its on pc.

I have many consoles but sometimes its just easier to play on PC , no need to plug and unplug everything

Easier with Pc

gotta have the feeling of a controller, i used to strictly play console.
but now that you can just plug a controller into most computers and map it out, its nice to be able to use mods
