Thunder was the first I tried two weeks ago but didn't really like it at all. Maybe it's time to try it again, though it seems I have trouble logging in on it now.

I used to like Liftoff the most, but something changed in the last update and I don't like the new appearance of the feed as much.

I still go between it, Jerboa and Voyager and sometimes Connect. I don't like how Liftoff handles replies in the inbox, for one reason. It also shows only combined votes, not separate up/downvotes, while Voyager and Connect require an extra click to vote/reply to comments.
