I liked it for PC because on PC, you can mod it. The vanilla game isn't too good.
It has a little option that makes the game harder as you grow in levels, which is kind of horrible. You can easily finish the game as a level 2 character, while as a level 40, it'll be near impossible to finish.
I would'nt get it for XBox 360. A PC version on the other hand, is pretty awesome and I've spent days playing it over and over again, trying different combinations of character builds and combat tactics.
