lol nice XDD
okay, since I wanna add my own opinion...
Best repaints;
Universe 2.0 Ratbat - for some reason this version of the Noisemaze mold just...works. When I saw the coloiur scheme for the original (both Noisemaze and Sideways), and while I do like Noisemaze a bit more than Hasbro's version of the paint scheme, just didn't fit the character.
RiD Scourge - taking as a guy who has owned both cabs from Laser Prime and Scourge, I can tell you I prefer Scourge's colours over the Laser Prime any day. The teal and black just work together perfectly. Not to mention the red light-piping is just delicious.
Flash Lio Convoy - What? Translucent gold and white plastic with sparkles looks cool. Right?......right?
Worst repaints;
Botcon Thunderclash - good......f--king.....god. I love the figure, but there are days I wish I'd bought Flak instead. This mold looked way better as Rodimus; the white and turquoise go about as well together as Aerosmith and Micheal Buble, and the decals - while working as an homage - don't work with this toy.
Orion Pax - this toy is a mixed-bag. Yes, I understand this is what Prime was supposed to look like before becoming "Prime", but again did he look old and cranky like Kup? Probably not. The whole Prime look on a Kup is both surreal and kinda distracting personally. Not saying the idea was bad but, coulda been better.
Animated Rescue Ratchet - As Vangelus put it, he looks like a crossing guard. This Ratchet was trying to homage the movie Ratchet...and failed. Yellow is wrong, face looks horrible. Glad I bought the original version that mold.
