Forgot about that guy, RTS 2 pack Cyclonus is indeed awesome. Don't much care for the Universe one, and the Henkei one better but a little bright, but RTS is perfect. If your going to repaint a toy as the same character that's the way to do it.
I think playability is pretty subjective issue, I don't see those two toys as having features that impede playability myself. Maybe for the Gok brand of playabilitybut for me they suffice. Jazz is my absolute favourite of United and I have no problems with his torso, it doesn't hinder me from posing and reposing him to fight the Decepticons. Preceptor I find similar, though he' not in my top 5.
I have a greater issue with Tracks backpack, which seems to come loose the moment I go to repose his arms or legs, of Grapples crane arm that just gets in the way, and makes his army pop of at the elbow whenever I pose him.
