[quote name='Jackovasaurus']Is it true that AMD drivers are a pain in the ass compared to nvidia? That's what I've always heard.[/QUOTE]
The advantages of Nvidia drivers I can think of right now are user-modded drivers, Ambient Occlusion (AO) and PhysX.
There is a much larger modding community for Nvidia cards than for ATI. These modded drivers may enable all sorts of settings that are usually locked, tweak performance or allow a user to force an updated driver that hasn't officially yet been made available to a specific card. It's not something most people care about though.
Regarding AO, it is a shader technique (I think DX11+) that can make some 3D games look more realistic, although it has a huge performance hit. For a lot of people, their FPS drop to about half of what it was without AO. Nvidia users can set AO on/off in their control panel. ATI cards can use AO if the game has the option, but forcing AO on other games will require some modding. Perhaps a future Catalyst update will allow the option.
As for PhysX, it is a physics engine used by some games. It allows calculations to be done by the GPU instead of CPU, and can improve visual effects such as glass breaking. The last I recall, Nvidia made PhysX work only on Nvidia cards (there was a patch to bypass it, but I think Nvidia got around it). I don't remember if they ever lifted this restriction or not. There is a way to get around the restriction with an ATI/Nvidia hybrid setup and a mod. But in the end, if you really want PhysX, it's much simpler to get an Nvidia card for now.
Overall, there are some advantages to Nvidia drivers. But those advantages tend to come with a much higher price tag. They are generally only useful if you're one of those people who like to max all graphics, often forcing it beyond the in-game options.
