They're all good if the benefits fit your play style, and bad if you'll never use the benefits. All of the drawbacks can be (nearly) overcome by just investing points in Max Arousal or Willpower, so think of it as sacrificing a few levels for a unique perk.
I think the worst one is Succubus Sex Toy, because its benefit, being better at penetrative sex, is directly countered by its drawback, losing faster to penetrative sex. That said, it can also be overcome indirectly by just investing more points in Max Arousal.
