Voyager is the best at the moment. There are a few other full featured ones. People always recommend Jerboa but when I looked at it I think it was lacking moderation tools. I’ve also used Sync, Thunder, and something else. You’re on the right one now. No need to change.
The only feature that I am after still is the ability to browse other instances without searching. You can’t do that yet in Voyager.
Are you having specific trouble with something?
Is this in reference to a particular IP?
