Choice between Aneros Eutho Sin and Vice

Newbie. Almost. Tried Aneros Helix sin last year. Felt good. Did develop an unusual and pleasant feeling, but got weirded out and tossed it. The one thing I did notice is the tip of the helix felt like it just barely touched the prostate. Now I want to try again but want maybe some advice whether to go with the longer Eutho w/o vibrations or the bigger ice with. I’m very much interested in the kegel exercise, but intrigued by the notion of additional stimulation. A big question is with the vice w/o the vibrator turned on can you still get the same back and forth massagejust with kegel clenching? I mean it’s shaped different isn’t it?

thanks in advance for any experiential wisdom
