White's just..."play white. Play more white. Hope your opponent doesn't have Dread of Night or a deck that's actually good. White, white, white."
With that being said, white does have some pretty glorious bruisers that can win you the game. As long as those are the only white cards you're playing.
About ten years ago, I would've said blue was my favorite without hesitation, and I would've said green was my least favorite. Nowadays, black and green are probably my favorites, less for the flavor or the colors' "COLER PI" aspects, but more that they both synergize really well with pretty much everything, and often have the most useful toolbox cards to make decks work.
I'll always have a soft-spot for blue, though, even though I don't have the dime to play it in high concentrations in competitive decks.
