Having see the pics myself:

Onslaught - love it
Prowl - love it
Octane - like it; the other name will not be used by me!
Powerglide - don't like it at all, which is a shame
Sunstreaker - such a good concept, but such an uninspired final product. As much as I want a Classics Sunstreaker, I am not convinced by what I have seen.
