The PC edition will generally allow for better graphics and such, but is also the most glitch prone edition. If you want a slightly less quality edition that is more likely to be bug-free, go for any of the console editions. The PC edition holds the record for the most game-breaking bugs.
PC. I don't really remember any glitches. You can also change a line in a notepad file in the game files, and easily unlock the DLC for free. It also has 60fps, but I think you have to unlock it first.
Actually, the amount of glitches is unreal for the PC editions. People who didn't get glitches were really, really lucky. The umbrella glitch was game-breaking and caused so much stress for some people. More recently, enemies didn't spawn meaning Alice couldn't continue to the next level or section.
