Honestly I have tried both and there are two main differences - size and power. The size may be nicer but its nowhere near as strong. Honestly I have a third option that I prefer a hundred fold over both others -the couture inspired by cal ex because its silicone and its small enough to use during sex and its basically like the hitachi on low - definitely enough for 99% of women.
I have a few - the only issue I've found us that with daily use the cord can short out but that's about it. Plus it's a decent price- almost always on sale on Eden
