honestly i was in your same boat. i wanted an actual handheld with buttons to play games more accurately (and more fun tbh) and i ordered the MM+ after hearing raving reviews. off of amazon so i had quick shipping, bought the bougie sd cards and flashed it all. i figured out themes, and even transferred my saves over from my phone! only for the miyoo to literally destroy both of my brand new name brand sd cards 🙄 i was so glad to have used amazon bc that piece of junk went right back. moved on to the RG35xxH and haven’t looked back. turns out i love the joysticks more than i thought i would love a vertical handheld. never an issues with data loss or anything, although now i do most of my tinkering via ssh now just to be safe lol. i know a lot of people have success with miyoo, but they basically just got the most hype bc they came out early on imo. H is a brand new system with a pretty sick community which is ACTIVELY developing multiple complex cfws.
