I'm all about the swarm. The macro mechanics are sooo good, and because of that I don't really enjoy toss or terran. Patiently waiting and anticipating until the moment comes when you can get right up in your opponent's face with a nice surround... controlling the entire map with 4 bases to 2...absorbing everything that's thrown at you with the good 'ol wax on, wax off...yeaaaah.
The grandmaster of casters, Diggity, once described the personalities behind each race as
Terran: rock and roll, super destructive, power power power
Toss: blinged out in tech, super cool
Zerg: primal, creative force, wave of nature, very zen

Zerg just make me feel like I'm evil.
I felt that way as a kid w/ SC1, but when you get into the pro/competitive scene, there's none of that campaign feel. It's very neutral, just skill based.
