As others have said, there really is no "best". We have been in all types with a 35' MH, 3 slides. Some sites are harder to back into, some are tighter side-to-side. Location is the key; do you want to be close to the waterfront and boats to the MK, or the outpost? We have never had a "bad site", however we do not reserve the preferred loops anymore and generally request the 800 loop for premiums or 1700 loop for full-hook-ups. When you check in ask the CM for an easier site to back into if that is important, also consider if you want to be close to the comfort stations or bus stops. They are great at making guests happy!
