MGX or return to old Progasm?

About a year ago I had a Progasm that has since left me. I had made decent progress but no orgasm, mainly just some quite pleasurable waves. I could tell an orgasm wasn’t too far away though.For a number of reasons I stopped, and now want to return.

*Should I buy another Progasm considering it kind of worked for me? Or would a different model be a better choice to get (possibly) faster progress? I was thinking the MGX trident…*
