I've been playing games on PC since roughly 2008.
It's definitely more convenient in a lot of ways to have all your games at the touch of a button, and there are many other advantages like price, moddability, etc. There also disadvantages like how some games might run for you without technical support or how you might have to turn down graphics since stuff can't be tested across all pc's and thus you don't have the reliability of a standardized console.
I guess I lean most towards pc for the sheer convenience factor above all else, though in the end it's not a big deal. Ultimately I just like to have all the good games I can get that tickle my interest, and one way or another you really need to have every console and gameplay device if you don't want to miss anything.
I'm personally going to wait on PS4. I usually like to wait on new consoles until there's at least several games that I really want. For example I could have gotten a Wii U for Super Mario 3d World + Wonderful 101...but I figured I'd wait till Bayonetta 2 comes out as well.
One advantage of the consoles is that the controllers have rumble. Yeah.
