What are your favorite artifact rewards?

I'm always slightly disappointed if I go through a game and don't get Drone Command and Sky Chitin.

I'm a Builder at heart and play a defensive style game, so for my early game gambits I'm always hoping for Frontier Stadium and the Tesseract Targeting. This then allows me flexibility after researching Computing as to whether I need to go for Ballistics, or if I can comfortably take the leap towards Autonomous Systems - classic "A game should be a series of interesting decisions" moment!

Those are definitely two of my very favorites.

Clearly "Slumber Slaughter Extract" (+50% worker speed). Also very nice is the +25% spy mission speed (forgot the name of the artifact reward), and of course the Frontier Stadium
