I'd feel more comfortable listing the main lines from best to worst..
1. Shockwave - Incredibly screen accurate and articulate; looks great in both modes2. Ultra Magnus - About as cool as Shockwave
3. Prowl - So much better looking than Hasbro's Smokescreen
4. Grimwing - Really nice looking mold.
5. Voyager Predaking - Super awesome in both modes.
6. Voyager Optimus Prime - Pretty okay, but needs some work
7. Lazerback - He's being Lazer back!

8. Ripclaw - Nice mold; should've been Serket
9. Bulkhead - He's.....okay looking....ish...
10. Wheeljack - Same as Bulkhead
11. Skystalker - Looks nice in dragon mode, kind of awkward in robot mode.
12. Vertebreak - Not as good as Lazerback.
13. Ratchet - Nice homage......looks like ass.
14. Arcee - Again, looks like ass.
15. Knock Out - Same as Arcee
16. Megatron - Same as Knock Out
17. Starscream - Same as Megatron
18. Soundwave - Same as Starscream
19. Bumblebee - Same as Soundwave, but I love the bow
20. Night Shadow Bumblebee - Nice try, Hasbro, but no.
21. Smokescreen - Takara's is superb compared to this ugly chunk of kiddie-menu-colored garbage. Gross!
22. Dreadwing - The ugliest piece of crap in this line.Also, I disagree with you on "More interesting than PRiD." That line was full of Gems, with the only "craps" being Starscream, Bulkhead, and Airachnid. For Beast Hunters, it's quite the opposite: full of craps with the only true gems being Shockwave, Ultra Magnus, and Prowl.
