Same here, I wasn't even familiar with the various other names that came up when the API drama exploded. I didn't realize there were so many. I've never even tried the official app.
I still use old.Reddit on desktop, though I'm now expecting that to go away sooner rather than later and that'll be the end of Reddit for me. Unless they come up with some whole new unexpectedly awful decision before then that I haven't even thought of yet.
