Dunno - I reckon there are a lot there better than a lot of the current half-transforming Cyberverse ones. I found Powermaster Optimus and the original cars like Jazz and Prowl to be good fun even years on.
I'd say the
worst ones in my collection are
Energon Mirage,
ROTF Scalpel and
Alternity GTR-Maximus. They are all ones I gave up on trying to transform properly. It's especially annoying with Maximus as I paid over a hundred bucks for him and only ever got him half way though his transformation. He has been sitting in a crate looking deformed for years now.
