afaik, jerboa's the only option. I actually like the UI for lemmur, but it's abandoned and doesn't seem like anyone's forking + updating it so for the time being, we only have jerboa.
I did see a toolkit that translates reddit API calls to lemmy API calls, which might be useful if any reddit app dev has any interest in translating their app to work for the fediverse, but I'm not sure how likely that is
