Whats the best airsoft gun?

i need 2 airsoft guns that shoot 350 350 fps with .2 g bbs or less. I want it mostly metal so if the gun has problems i can take it apart instead of the plastic crap that cant be dismantled. I'd like one to be electric and the other spring. Buying from websites is always hard because I am only given biased information from the seller rather than true defects. anyone know of guns fitting my description?
