Either speaking statistically or for flavor, what are your favorite abilities to choose for your custom races?

Mine would have to be Industrious with maxed research and at least +1 flight speed. I just can't seem to justify exploring the galaxy if my ships are of average speed. Plus, I love the ships, I can't get enough. I build one for every situation, so I always try to pick up +1 - +5 in ship building.

I don't really have flavorful reasons for choosing those, but I do tend to think my civilization is simply built for the stars. I feel that if I chose too much in +ship weapons, or +invasion that my race is just too war-like, so I tend to shy away from those. Yeah, it helps me sleep at night.
