Like others have said, it depends on what's comfortable to you. If it was my money, these are the markers I'd look at...
1. AKA Viking or Excal. Good trigger, easy to adjust. Fast as heck (now that the BPS cap has been removed). Extremely reliable. Low pressure operation so it doesn't need an eye. Good support from AKA and simple to fix if anything goes wrong. Doesn't need upgrading. Fairly unique. Unlike Angels or Impulses, you won't see 10 other people with them at the field. Downside is they're not real bling-bling flashy.
2. Oracle E-class. Fast, fancy, accurate, anti-chop eye, high bling-bling rating. Downsides would be they're higher maintenance and kinda pricey.
3. X-mag. Haven't tried one yet but they look good. Fast as fock, lighter than the old E-mags, nice trigger (based on my old E-mag), no breaks with the Level 10 upgrade (don't know if it comes stock on the X-mag). Good bling rating.
4. Custom Impulse. While personally not a big Impulse fan, some of the custom versions look very nice. Adrenalin, Eclipse, Voodoo, Strange - lots to choose from. Anti-chop eye is nice too. You do see a lot of Impulses out there, so the uniqueness factor is going to be low.
Whatever you get, make sure you know how to take care of it. I always recommend checking local shops first. You can get a better feel for it and take it back if you have any problems.
Then get a good hopper (Evo II or Halo B) and some good barrels. Boomsticks are good, and I've been really liking my new Ultralite, or one of the multi-bore sets (Freak, Pipe, etc.).
Edit: Almost forgot... make sure you have a good air system to power your new love child. A great gun with a poor air system isn't going to perform that well and you're going to end up disappointed.
