Obviously Winter Melon because:


 * He can slowdown, and slowdown = DPS damage doubles.


 * He can damage groups of zombies, and group damage = Damage to a lot of (pesky) zombies.


 * He is more cheaper than a Gatling Pea + Torchwood, and more cheapness = Early defenses.


 * And even being Repeater + Torchwood combo, he would win because the combo can't be eaten later, and it occupies 2 tiles, instead of one, that means that Torchwood can be eaten then Repeater goes down to a crappy guy, and more space = MORE PLANTS!!!!!!!!!!!!

So Winter Melon wins easily here.
