I've had a Sona, a few Womanizers, a Satisfyer and a recently deceased Clitorizer - I'm honestly not bragging, I just love them and have managed to wear a few out.
Well, all except the Sona. For some reason, it just takes absolutely ages to draw an orgasm out of me, which frustrates me as with the others I'm done and dusted and going back for more in under a minute. Can't ever see me wearing the Sona out!
They're all similar in sensation to me (even the Sona - sort of), so it's a matter of preference and budget.
I recently exchanged the Fifty Shades Freed one for a Starlet as it did nothing for me (though it might have been faulty). I didn't want to get stuck with another Sona-like disappointment so got the Starlet to use when away from home.
I'm a bit gutted as the Fifty Shades and the Sona are lovely toys and feel a much better quality and so much nicer than the Womanizer or the Satisfyers in the hand (though I haven't tried the Womanizer Premium...yet!). But it's what they do between the sheets that's the most important thing.
