I always find a fast modern IPS panel to be the best choice with decent response times that can now compete with TN panels, excellent colours and a wide viewing angle (not that you'll be gaming sideways at your desk). The only downside really is IPS glow that can be a bit distracting if gaming or watching a movie in the dark, but some panels are better than others when it comes to this. I can also say that VA panels can also have a glow similar to IPS, but their pixel response times are slower...Especially when transitioning between bright and dark images/scenes/objects. This produces the known VA "smear" effect that that can be distracting after you notice it.
TN panels are great for pixel response time and the colours and image quality are not as bad as they used to be, but still not what I'd call great. Viewing angles are narrow when it comes to colour shift etc..., But like I said, you won't be gaming sitting sideways (I hope). I would always go for a decent IPS panel over TN or VA. They also all use LED backlighting these days.
