I use it more or less to browse my multimedia files. Ranger knows if it’s a pdf or a mkv file, so I don’t have to do anything but hit enter. When watching a series, I hit Q in mpv, down arrow and enter to play the next episode instead of writing mpv tab tab enter. It’s also got pretty nice tools for mass renaming, deletion, and probably a lot more that I didn’t bother learning. But if I want to get a specific file, say a config file, then I just open it normally with an editor from the terminal instead of going from /home to / to /etc
