Personally I don't think yellow paint apps for Primes lights improve the toy at all, I think Prime looks best when they confine the use of yellow to his lower torso, too much just doesn't look good.

I think the Taktomy one still looks a little more classy than the Hasbro one, but as the Hasbro one is cheaper (and I already have Takara's original MP Prime) that's the one I will get.
