tough one but even though she isnt as crazy as dru she can control dru and shes very manipulative! but you see more of that side of her on angel!

Yeah you are right there. She's stronger and maybe cleverer as Dru. Because Dru with her "little" craziness. But I like them both, especially in Angel.

Dru is really kind of weak for a vampire, although she is quite sick and twisted. Darla would know well enough to avoid eye contact with her and seriously whoop her ass.

nah i'm gonna side with Dru here she would own in a fight!
