Well, do you have a preference for a bodyshape? Classic (like LP or Viper from ESP) or Modern (MH or Soloist) or extreme (EX from ESP or RR, KV, Warrior, etc)
Some other aspects: IMO, Jackson necks play faster, ESP have better pickups (or the pickups I like, I also have EMGs in my Ibanez), I prefere Jackson bodyshape (King V or Warrior customs are my dream guitars)
For the rest, its up to you. You're going to spend 1000-2000 bucks on a guitar, so it seems like you've already started playing.
If you're going to start playing with this guitar, dont buy such an expensive one yet, and if you already have one, also think about a proper Amp etc...
