Super Freak
Cliffjumper is definitely the nicer looking of the two in robot mode but both alt modes are great and if the Bumblebee headsculpt gets improved by the time it's released several months from now then I don't think there'll be much to choose between the two.
When Brawn's proto was first shown it got blasted on sites like TFW for missing a point of articulation on the arms and iGear took the criticism on board and changed it so they may do likewise for Bumblebee's head.
I hope they do re-work Bee a bit would prefer him to look a little better.
I have a scary feeling that iGear will do something similar to what they have done with Gears & Beachcomber...sell them in 2 packs one with Wheelie & the other with Powerglide so you can't avoid having them all
Oh well we have a long wait till they arrive so I'll keep all speculating to a minimum
