Spire every time. My rotor packed up on me several times, whereas the only time my spire stopped working was when I had a break that caused chopping all the way into the bottom of the hopper. Even then it was trying to push the mush through
Rotor all the way been playing for a few years now and seen many others have problems with there spire’s the rotor is just bulletproof and the battery life is second to none
Brilliant design, ease of field stripping/cleaning, rhobust construction, ability to take 50cal with a kit, jam clearance, sheer speed and battery life. Had mine ages and I don’t remember ever changing the batteries
