>>6133758Pretty much any of the original Headmasters are good, though theres a bunch of possible QC errors on any given one of them.
Highbrow suffers from a floppy neck connector, but that isn't a QC error, but a design one, because Highbrow (and Scourge, his moldmate) have raised neck connectors for whatever reason.
Avoid Galvatron, he's pretty shit. Blaster is better than Soundwave, and Astrotrain is good, so is Sentinel.
