I've actually bought a couple of 1987 G1 headmasters in the last weeks: Chromedome, Skullcruncher and Weirdwolf, and I already own Mindwipe, Snapdragon and Apeface. I also own Predaking, and if I'm honest, Predaking is a way better toy than the Headmasters, in all respects. A lot more impressive as a display piece, better play value, better designs.

Don't get me wrong: the regular Headmasters are pretty cool in their own right (especially the triplechanging Horrorcons), but given the choice your are stating, I'd choose Predaking every time.
