HZ H4 pick ups on kirk hammet 202

do the stock pickups (EMG hZ H4 humbucking pickups) suck are they worth keeping I want an 80's metal sound also does the licensed floyed rose like suck or is it going to be ok. I ordered the Ltd KH-202 but it hasnt came I am thinking about canceling the order and getting a Jackson if I did what is a good jackson with a shredder type body not a flying v I like megadeth and they use jackson so what should I do keep the one I ordered or go with Jackson O yeah what the hell is Kramer?
