MGX vs. Maximus

I own everything from the sgx to the progasm. I think it comes down to personal preference. Personally the smaller models work better for me.

I dont own a mgx but do own most models. In saying that the maximus is the best all rounder ALL the time.It never goes out of fashion with my body. Others change some times there good other times there not but maximus fits just right every time. Progasm Ice next and them largest peridise.
Maximus is bigger than mgx so it will simulate more nerve ending at a time as long as your muscles are trained up enough to get the toys moving.
Eventually your body will tell you which device it wants. Your heart just desires one over the other.
As for precum that depends on how animated the device gets which revolves around your muscles again. How strong they are.
