its going to depend on your play style and if you want AOE or not.
So give a little speech about what you expect/want and then advice will come rolling in.

I arbitrarily recommend the mesmer over the thief. This is because the population in general seems to prefer mesmers to thieves. mesmers bring a lot of utility to a group (mainly portal, feedback, and timewarp) and are generally well accepted everywhere.
Thieves are not. Several months ago there was a nerf / buff (depending on your viewpoint, it’s complicate) to stealth where the enemy would not drop target when you stealth. The net effect is that invisibility is now less useful in PvE. The enemy just stands around and waits for you to reappear.
Anything I post is just the opinion of a very vocal minority of 1.
