Which one?

I’ve read all the threads I can find about which is the best model and the best one seems to be the progasm, but I understand everyone is different. I’m not super inexperienced, I have the nexus g-play large which I’ve used a bit.

I’m not willing to purchase two of these things at the moment so I want the best model I can get. Even if the progasm is too big, is it something you can learn to use? I’d rather not go with the jr if the original is ultimately better once you’re used to it.
