EmuDeck is the more featureful one, but messy in a lot of places - and definitely not just a flatpak. I particularly hate how the ~/Emulation folder is full of absolute symlinks (even when creating sibling folder aliases!) to random places, so it can't be properly used with Syncthing unless you write your own ignore files and set up shares per emulator save directory. Their Windows version is also not exactly the same, so syncing media between a Windows machine and a Linux one is even more annoying. RetroDeck bundles everything into a single flatpak and seems a lot saner, but is a lot newer.
