i also own both but i'd say in terms of stripping it just to allow you to clear it out quickly then they are both just as easy. but to fully take them apart then yea the rotor winsI have both. Both are nice to use but when the time comes to field strip your loader because of a ball break inside or getting shot in your loader, then the Rotor wins hands down.
you don't have to buy a new top shell to have a speed feed on a rotor mateBoth great but personally, the z2
Cheaper to start with and even cheaper to buy a speedfeed instead of a speedfeed and a whole new top shell. Automatic ball unjam, works with reballs, ripdrive. Only upside to rotors in comparison personally is its slightly easier to take apart.
