What are the best mp5’s?

Hello, I’m new to the community and I already have a couple of guns, bb and airsoft. I don’t really go to fields, I just like to collect them and shoot them. One of my favourite guns is the mp5. I want the most recoil highest fps mp5 available even if I can’t use it on a field. I’m open to gas, elec and c02. I assume the options yall will tell me are expensive, so if you have time, along side your recommendations, what is a budget friendly but still solid mp5? Thanks!
