Its gotta be said, if anything my thread has made me more confused with positive/negative comments regarding the same thing.
My own experience with Nvidias 3D vision was that it works a treat, obviously some older games have certain issues but the majority work fine and "3D vision" ready games work brilliantly. Can I suggest you have a look at the 3D vision blog website found here as you'll certainly get less biased opinions over there than you ever will here. Another page you may want to have a quick scan of is this, although slightly outdated it gives you a rough idea on how well each format is supported.
