Dru gets a bit more screen time in AtS, and her relationship with Darla is pretty interesting there.
There was a poll once that ended up with Drusilla ranked above Darla in "favorite vampires" and one fan who was hugely into AtS could not figure out how that was possible. Obviously, it's because Darla got almost no time on BtVS. I think she should get extra credit for just the first 5 minutes of the show, but if you don't watch AtS, you definitely don't get her full effect.
(I know you're not too keen on watching AtS, which is understandable, but I could steer you toward the episodes that might appeal to you, if you think you might want to sample.)
