From what I've got so far:

Onslaught = Very slick! Can't fault him in any way! If you've played with a TFA UM, he TFs pretty much the same way

Galvy = Yes he's a little small, Yes he seems over-engineered but Yes he's also pretty damn cool!

Prowl, Streaker & Octane = *big tick*

I'm waiting for a red Powerglide & white Silverbolt and I know I'll be impressed with Powerglide & not-so-impressed by Silverbolt but Eh... I luv me Classics!
