New to Lemmy! Is Eternity the best Lemmy app?

There is no best, just ones that fit with your style

I tried Liftoff, Thunder, and Voyager and settled on Voyager after Liftoff broke.

Best is obviously a subjective question. You can find a list of apps here. I like and use eternity but voyager, thunder, and sync are all very popular as well. Just download and try them and stick with whichever one you like most.

Also keep in mind that most of these will be configurable with themes and other interface settings, so if you like an app except for that one thing, you might be able fix it yourself
