This is a tough one. I love third person shooters, especially Jet Force Gemini and Gears of War, but the problem is that few developers put enough time and energy into those projects. First-person shooters get more attention and thus produce better games. My top 25 has something like five FPS and zero TPS. I don't think that has anything to do with the sub-genre per se; I think it has more to do with the priorities of developers.
So, in other words, I think FPS is the more successful sub-genre, but I don't think it's intrinsically better than its third-person cousin.
