Differences or pros/cons between Morpheus8 and Pixel8?

I have seen 2 different PS who each offer different RF Microneedling treatment. Neither Knew about the other brand, nor could tell me the difference between them. I’m 36 yr old and looking to tighten my loose neck skin and jowls. There is quite a difference In price as I’m being quoted $800 for pixel8 for both face & neck and $2000 for Morpheus8. I don’t mind paying a higher price for a far superior product but concerned this may not be the case. professional opinions would be appreciated.
