Personally, I'm pretty split on this decision. I like them all for different reasons. Though, honestly, I'm leaning toward Eldar at the moment. Additionally, I'd be interested in seeing this poll go up again shortly before launch, after more details and specifics are revealed, to see if people still hold true to their choice once the chips are down.
Chaos Marines, no one takes better cares of, had more fun with, or loves thier followers more than Grandpa Nurgle, The Lord of All.
Orks! Oi! You can kill an ork, but you can't defeat us without Exterminatus! So have fun virus bombing every planet in the galaxy! HAR HAR HAR! DAKKA DAKKA! And more like that. LOL, orks aren't very sophisticated, but it's very difficult to eradicate them when you have them on a planet. That because orks are spores/plants and when you kill them they release spores, given enough time the spores develop into orks (wildboys) and because ork know-how is genetic. So eventually the will come back with ork tek! So orks are brutal and tenacious. Though I also like Choas space marines and Eldar. Don't like those Corpse worshipper though!
Well I play SM and Nids. So I obviously can't have my Nids for understandable reasons so I must go with the Emperors finest. Although I will end up playing them all.
Everyone will stare for a minute at Eldar Farseer Boobs, then the majority will proceed to try and create their filthy Smurfs or Dark Templars!
