I've been using Jerboa so far. It's pretty nice. At first I was a bit sceptical because it seemed a little half baked. But it's growing on me. Also now that I've used it for a while I think it's relatively well rounded feature wise. It is quite minimal, but I think a lot of people probably like that. I think long term if other apps come up that are more similar to the existing 3rd party Reddit apps I will probably switch though.
My main issue so far is not being able to follow links to communities inside the app. I imagine this will probably be more difficult to implement than on Reddit because of federation, but hopefully apps can get that working eventually.
Also it can be difficult to add new communities from other servers even via search. Which is also a federation issue.
I also miss the features from Reddit Is Fun which let you choose which content is displayed in-app vs in a web browser. But that's only a minor annoyance so far.
I find I am getting used to the visual style of comments. I initially didn't like it, but it's growing on me.
