This is the exact opposite I've felt. The rotor and Z2 are tanks compared to the spire in my opinion. That being said I have a Spire now. For some reason I would always get 4-5 balls stuck in the nose of the Z2 and would have them break or melt since I didn't realize they were there. Happened 4 or 5 times before I sold it. Plus, the ease of taking apart the Spire is too good a thing to pass up. Have a rotor with a soft arm as my back up and love it, just loud as hell when i'm out of paint.
All in all, you really can't go wrong with any of the big 3 and the "winner" will always come down to personal preference.
