(Ok, this may be a little ridiculous, but still works as a valid enough thread)
For those that don't know what am I talking about, these were the three pokemon available for a G/S alpha demo. Two of them were mostly scrapped while Happa became Chikorita.
Besides their types (grass/fire/water) and a few moves, there's really nothing beyond looks to vote... So asking which would do better is quite pointless.

I voted Kurusu, by the way. Honoguma has by far the best design, but I like the simplistic and cute design Kurusu has.
