I was originally planning on getting it for PS3, but dear God, it's outrageously expensive in my country (around $120 USD). So I ended up buying it on Steam for the much the better price of $50.
I really love it! Because my computer only meets the minumum requirements and not the recommended it's not as graphically powerful as it is in consoles normally, but it still looks very, very good. Game flows really good, very good framerate, and the keyboard/mouse controlls (by default) are surprisingly efficient and good. Controller still beats it all day, but if you don't have one at hand, using keyboard/mouse isn't bad at all.
All in all, I think it's really good, no better nor worse than the console versions. With the only downside that the devil trigger and gun special commands cannot be changed from the default and that the menus force you to use arrow keys instead of the mouse.
The big upside, of course, is the mod support that will surely show its colors soon enough.
