I tried out 3 apps total and even with it being a little stuttery, Jerboa has been my favourite so far. I like the layout of the interaction buttons for comments as well as the ability to jump from one comment chain to the next or previous.

I found Thunder to be a very smooth experience but really didn’t like that you need to swipe comments to interact, and that the distance you swipe determines whether you upvote or downvote or etc. Perhaps there’s a way to change that in the settings but I couldn’t easily locate it.
