Hi!

IMO Super Breeder, because:
- your pop grows so fast there's no money crunch in the colonizig phase of the game (you simply never run out of money, just don't build everywhere immediately);
- at the end of the colonization phase you easily can have more pop as the rest of AIs together, so you can start invading their mostly below-100M planets (which will start paying for themself only in about a game-year) WITHOUT any significant dent to your economy.
- you can never run out of troops. Having just in-game pop growth bonuses (70% + a small bit from anomalies) I've breeded about 1B pop on each 2B+ planet each turn!
- invaded planets start payig for themself almost immediately (just dump 2B pop there), and start producing troops 3-5 turns after invasion.
- bonus tech from invasions comes really handy, so you can significantly decrease spending for research and "live" only by those techs. The more planets to invade, the more of those techs you'll get.

For more you can check Playing with lots of planets - how to financially survive first year?.

I think it's pretty clear that it's the torians or the thalians. Me personally I like the thalians. The missing peice for them, is getting numerous survey ships going very early, such that you can keep your expansion going. (also take max pop bonus)

Because that works out well for me, I don't see the need to play the Torians. (I don't really have much of a money crunch.)

The last possiblity is the the korath. If you can get going fast with spore ships you can roll. However in practice, at suicidal it's hard to hit them before their defenses are up. (at least for me)

The cheesy suicidal win, is to play the korath against just the iconions. It's rediculously easy to spore them out of existance...
