So I got the two pack and opened it up. AOE voyager is just as nice as the mass retail release. The Energon mold is just as I remember it before I sold it off a long time ago. The robot arms/dinosaur legs on the E. Grimlock are super loose though, anyone else have that problem?
I like the colors of the AOE 2-pack version a little better - more contrast and visual variety. Grimlock is fine (I'm one of the three people on Earth who like the Energon Grimlock toy) - a bit more G1-ish than the Energon toy, if a smidge heavy on yellow plastic. Mine has only one loose arm. The left arm doesn't want to stay slid into position for dino mode, but behaves otherwise.
