There is minor differences that each has. The best feature that I look for is swipe to upvote, compact view, thumbnails on left, clean inbox and messaging. Unfortunately due to the lag, anytime I post or want to save a post I go into the browser as none of the apps successfully post.
Jerboa failing to post (at least for me) is because you need to select the community when you try to post as it doesn't seem to auto select the community you're currently in to post anymore.
I've tried Connect, Thunder, wefwef and Jerboa so far and it's looking like Jerboa is my favorite so far.
