Sunstreaker is the most fun mp tilldate for the cars. It isn’t hard after you go through transformation once. Megatron is a totally different story.

Mp-10 was never in my books as the perfect prime. Both Takara and hasbro lacked certain paint apps and eyes on Takara version were most dull.

I gotten myself a cell shaded version of mp-10 and that might be my last Optimus if version 3 isn’t great.
