Anbernic RG353VS - I'm using a third party OS and it's my go-to handheld when the steam deck is inappropriate. Fits my hands and plays my favorite games. I love it for GBA and SNES.

PowKiddy RGB30 - second choice. I like the bigger screen and it's a 720x720 screen that works great with game boy. I use a third party OS and play a lot of Pico -8 stuff on it too.

PowKiddy RK2023 - Adequate, not Great. Boots slow. Doesn't feel good in the hands.

PowKiddy v90 - practically e-waste. Processor too anemic to run SNES. GBA emu was fine. Plastic so cheap I fear the stupid thing would shatter with a short drop.
