Just got WFC Soundwave and Megatron today, and of course I had to decide which of the 4 WFC figures I liked the best. Soundwave won.
I don't have any, but if I got one it'd have to be Megatron. He looks so cool, so does Prime, but not as much so. Bumblebee looks tubby with little stick legs, but the computer mouse mode is nice (not too ergonomically designed, however) and Soundwave looks like his got a beer gut.
I love this version of Prime hes my favorite so far next to War Within Prime. They are all pretty cool but G1 Megatron is by far my favorite.
Since I'm not fortunate enough to have a Soundwave yet, I'll say Optimus. He's the one that piqued my interest in the other three. This is the first Optimus Prime I've seen that really looks like a "warrior". He looks bulky but fast, and has incredible details sculpted on him from his six-pack abs, his autobot tattoo on his back (which you don't even get to see most of the time, and btw, Megs has a similar Decepticon one too)to a pair of antennae that would make Batman have cowl envy. Even his alt mode is aweome. Especially when you realize that you can flip his kneecaps around and give him tail-lights (not in the instructions, thanks Hasbro). Sure it looks like Hasbro dropped a possible melee weapon(s) probably due to safety reasons, even without it, this Prime rocks.
I only have Op and Bee so far, so I'll with Op. Might change my mind when I get the other two, we'll see.
