I like the drow in Starfinder.
The visual theme is quite distinct and evocative. That would be hard to simulate. The contrast of light/white colours on dark/black backgrounds is very eye-catching.
The societal themes serve as a cautionary tale, too. They'd probably charge inhabitants or visitors for the air they breathe if they could find a profitable way to do so. Unless you're well-off in the drow corporations, you go through similar struggles as many people do, and that makes them extremely relatable.
