Progasm jr or ice?

I’m considering to buy either a progasm junior or the progasm ice,
I’ve got experience with anal toys but am rather new to prostate stimulation.
Do you guys have a recommendation which one would be better to start with or is it all the same since both of them will get me where i want to go with some practice?
(I do know that each of them feels unique, but since i dont have the necessary experience i cant really point out the differences)
