Which Womanizer clit sucker model is your favorite?

I have a friend that owns the Womanizer Enhance and it is pretty good. I would say the biggest complaint is that you can't move much or you'll lose the seal.

I am looking at getting my own Womanizer, but am not sure if I should just get the Enhance model or if a different model would be better.

I personally enjoy some heavy clit stimulation and forced orgasm, so power is most important to me. I don't care about fancy patterns and changes in speed.

Would love some opinions. TIA!
