That is a difficult question to answer. It's like asking a person, "What kind of vehicle should I buy?" The real person you should ask is yourself. What do I want from an AEG, what do I think looks cool, do I want to upgrade later or not, will this AEG work with the gear that I have? These are just some basic questions you need to ask yourself. Mohawk is correct, there are alot of discussions about types of guns here. Search them out and if still have some specific questions, please feel free to ask.
