For Lemmy apps, it's best to try a few for a week or so each—theres a few good'nes—and you land on the one you like. I was just plugging Thunder because it's sort of like the Linux of Lemmy apps. All the cool underground kids froth on it and those that don't use it couldn't give a fuck, because they don't know any better, man!

I've used both and have been daily driving Voyager for months, I'd say they're both great to the point it's a matter of taste. May as well give it a go if you're curious!
