I got the Reactivate toys, and have had a blast playing with them. These are easily some of the most fun toys to come out this year.
Some thoughts:
Soundwave: this has become my new favorite Soundwave toy, of any Soundwave. This guy is good. I love how stocky his torso is, the backpack and stocky stature give him the look of a communications guy who is carrying a lot of crucial gear. The limbs are good. His head is beautiful, though I wish his eyes were yellow like the box. Truck mode is very solid. Transformation is also good, I enjoy the way it wraps out and around. He's good.
Bumblebee: This guy is probably a top 10 toys of the year, and maybe top 5 Bumblebee toys ever. The reinvention of him as an armored Dune buggy is flawless, and the toy is so strong in both modes. Transformation is also really damn good. He lacks a wrist and waist joint, but those don't really take away from how good he is. This guy rocks.
Optimus: This is also a solid toy. there is some fiddle factor with the backpack components, and I think the axe was done a bit weird, but he's still very good. Not as Classics-Prime as i was expecting but still good. I really wish he had more max maxness besides the cowcatcher though.
Starscream: another banger right there. All the black looks really good on him, gives him a true illusion of being shot down and crashed. I love the headsculpt, the transformation is good, and the alt mode is pretty sleek. This clears the recent Siege and ER seeker molds to me.
If I had to rank them, I'd rank them:
1) Bumblebee
2) Soundwave
3) Starscream
4) Optimus Prime
