I do a lot of work with SQLite, and I do sometimes use one of the GUI clients (specifically sqlitebrowser.org). However, I mostly use the command line client that comes with SQLite, not because of how many features it has (not a lot) but because I use Bash and everything that comes with it, across various sessions managed with Tmux, as part of what I do with SQLite. It’s the same reason I usually use Vim in a terminal session instead of the GUI version. Using the GUI version means stepping away from a lot of my best tools.
