PC.

PC pros:

• Much larger game library.

• More control over games (modding, save game editing, whatever).

• Generally less-expensive games.

• Strong backwards compatibility spanning many more years.

• More hardware options. If you want more graphics horsepower, different resolutions, a vertical screen or some oddball resolution, whatever, going to have more flexibility on the PC.

• For whatever reason (high screen resolution? More memory? Mouse?) a lot of deeper sandbox and strategy games tend to be PC-only. Think, say, Oxygen Not Included. I tend to like those more than console exclusives. I'd like to have, say, HD releases of the 2D Metroid series on PC, but I just don't care nearly as much about them.

• In many cases, the PC can emulate older consoles (and thus has better backwards compatibility for a console line's older library than the console does).

• Access to games and mods without console vendor censorship or regional content restrictions.

• For a long time, consoles had worse loading time for similar games than one could achieve on the PC by throwing fast media and RAM at the thing. I remember playing though Fallout: New Vegas on both the PC and the XBox 360, and it was just a constant source of irritation. That said, that may have been largely eliminated these days.

PC cons:

• Less plug-and-play and more potential troubleshooting due to wider range of hardware and software interactions. Not an issue for me.

• More vulnerable to cheating in online multiplayer competitive games. I don't play those these days, but if I did, I might consider just playing those on a console.

• No remote power-on support on-controller if you're playing in the living room (the Steam Machine can do this if you're using a Steam Controller, but most PC hardware cannot). Not really something that I care about, as I don't living-room game, it's not much hassle if I did, and there are other ways to accomolish remote power control if I really wanted to do it.

• Less level playing field on hardware for multiplayer competitive games. Consoles don't have a "pay more to a hardware vendor to try to get a slight edge". I don't play multiplayer competitive games these days, so not a huge issue.

• Console games tend to take more advantage of hardware, since everyone has basically the same hardware and the console vendor can require everyone with the console to buy a baseline set of hardware. A console vendor knows that you have a game controller and that it has at least X features. PCs could have God-knows-what, so less-interesting to try to leverage features that only a fraction of the playerbase may have.

• Consoles have better isolation of games. If some game developer gets compromised, they probably don't even compromise your console. If they do, your video games get compromised, which probably isn't the most-catastrophic event. I do think that this is a real console win, but also that the PC situation has potential to improve (and some people on Linux do run an isolated Steam, which is a start).

• Consoles have better local multiplayer game library support. I don't do local multiplayer gaming.

For me, the PC pros outweigh the cons.

I've owned a number of consoles, and they mostly just wind up gathering dust.
