You can also run klipper on them if you want network connectivity. Granted you need a raspberry pi to run klipper so there is that.
After running klipper on my Ratrigs I can’t even consider Marlin anymore. Modifying a config file and restarting is less painful than having to compile and flash a bin for every modification or update.
