Not really a fan of the Decepticon symbol on Predacon Megatron. The Decepticons already have at least one Megatron and he doesn't seem like the sort to share names.
Other than that though, it's fantastic. Best looking version of the mold, for sure.
Primal isn't worth the money for me. The surfboard thing just seems like wasted plastic and it isn't that cool of a redesign. I still have Optimal Optimus and inexplicably blue BM Primal if I want a monkey prime, and really, I tend to use Armada Prime as a vehicle mode version of the Primal character usually anyway.
Unicron isn't something I'm interested in at all really. Looks ok, but not my Kup of tea really. He's too wee.
Axalon has a great mold and a pretty nice colour scheme as well. Nowhere near as cool as the Botcon Sharkticons mind you, but still pretty nice. In fact, seeing the comparison pic, all versions of that toy look good. And I still don't have one.
Don't think I'll get this one though.
