Both Iconian Refinery (16mp) and Fabricator (50% mp) are indestructible, also they lack soldiering techs, making them the best choice for your first invasion. Just thinking out loud here
Best races - 1st place Torian/Iconian, 2nd Korx who finally doesn't suck that much, then Altarian/Arcean equally bad. Note there where no wars at all, so Korx never had any extra income the whole game. Over last 2-3 patches Iconian improved most then any other tested race. They don't suck no more, actually they stay at the top, their research can get very high if left alone, as I experienced myself on 210 turn game - quite a challenge to keep up with them now, thanks to early game boost from quicker access to Library.
Next I'm gonna test AIP7 races, with Iconian for comparison.
