For me it's Ravens.

I even liked Science Vessels Quite a lot in SC1, and I'm sad to see Mr. Burns go.

But I love the little Sentry turrets for harass and clutch anti-air. And Seeker Missiles are awesome (though will be less awesome when everyone starts dodging them.) Even the point-defense drone seems to have situational uses; it's almost like an AoE defense matrix, or a limited-HP Dark Swarm.
