I did a deep dive into frontends because I love organizing stuff in general. I use different frontends for each device I have because they all have different pros, but overall my favorite is Playnite because of its metadata and sorting features. For Windows I use Playnite, on Linux I use Pegasus, on Steam Deck I use RetroDeck/EmulationStation, and on handhelds I use Knulli Firefly.

Playnite is imo the king, because it has really beautiful themes with custom cover art and can sort games in basically any way possible: by system, rating, genre, name, release date, you name it. The only con is that it’s Windows exclusive (for the near future) and is janky in Wine/Lutris.

Pegasus is spectacular for its fine grained control, and can be configured to do basically anything. Its like the Arch Linux of the frontend world; start with the basics and build from the ground up. With tinkering, it works great on almost any platform.

RetroDeck is great because it’s plug n play. I love to tinker, but I also wanted a platform to just play my games without hastle or messing around. I find myself actually playing my games on the deck instead of tinkering with the frontend.

Knulli Firefly is great for smaller screen handhelds for a similar reason. It’s very customizable, but also works straight away with little to no hastle. It’s also better than most stock OSes that ship with emulation devices
