It's not a client per se, but I turn Hexbear into a "Lite App" (very similar to a Progressive Web App, but supposedly has more features and customizability) with Hermit. Been using it for a couple months and no major issues, plus I get to keep the Hexbear UI that I've grown quite fond of
Thunder for Lemmy is my pick right now. It has a pretty clean interface and I haven't noticed major bugs. I only wish the hexbear emojis were smaller and the spoiler text worked.
