I think the re-paint wins.

The old face was a lot "RainbowDashier"...
and clearer defined i think.

Doesnt make this one bad...
but there was nothing wrong with the original either.

So its a thing of taste. No winners or losers.

I agree, though I prefer the old rainbow effect.

RD looks way better in this then in the previous picture for me

I like the re-paint's background clouds better.
How the sunset/sunrise makes the waterfalls look like magma.

Both pics have very different designs, like @ZombieFX said, no winners no losers, it's all a matter of taste.
I prefer the first pick in almost all aspects, but this one is definitely not bad. Still very nice! :D

Yes, I know I'm a late boy-o :P
