Oh... hmm... it's been awhile since I've used Razer, but I think the smidge more spatial awareness, outweighs it's cons over plain stereo. I just really don't like the limitations of stereo audio for games, UNLESS the games don't have multi speaker audio to begin with, like most 2D platformers, etc. Then I'll, of course take stereo over ANYTHING.
Honestly though, I'm not as anal about virtual surround gaming as I used to be, and do dabble with plain stereo gaming, if I'm playing very casually. What I mean by that, is for example: when I'm winding down before bed, and don't care about audio all that much.
I'm currently playing Valkyria Chronicles, and I honestly am not getting any surround cues anywhere with that game (even though it's supposed to), so I prefer stereo on it.
As far as virtual surround tech goes though, Razer Surround is bottom tier.
