I came from RiF and used Connect for a long time. It had issues with always bringing you back to the top of the page when you would leave the app. Eventually I've settled on Boost, and immediately paid for just on the basis that it reminded me so much of RiF (and it works!)
I just switched from connect to Voyager yesterday. I'm liking it so far but noticing stability issues. Like it crashes out every few hours or so. Nice to have mod tools back though.
There is no best. My recommendation is to download a bunch, then uninstall them one by one until you end up with the one that you like best. I settled on my favorite, and I had to give up some great apps with great features to get there. What do you value in a forum-style app?
That's what I use. Didn't want to influence your decision, but there's no harm in revealing it after the fact. I do feel like I missed out on some cool features from the other apps I tried, but Eternity was the complete package.
Eternity was great, but it's likely abandoned now. I switched to voyager. And this is a nice clean app. No complaints from me.
Worth noting that I tried all the available apps from the lemmy app list. And I've worked them down to 3 liftoff, eternity and voyager. Two of these are abandoned now.
Last tim I tried Summit, was months ago but to tell you the truth. It was one of my favorites! it's definietly better than thunder and boost. One app that i can compare it with is Eternity and Connect. The reason why it did not reside in my top three is because of my preference, there is a feel to an app that i am looking for, I really cannot describe it, I did not feel it with summit, but Eternity had it. But technically speaking. Summit is one of the very good apps for Lemmy, you will not regret it if you choose to use it.
to be frank, Voyager is the least of my three. Eternity did have all i was looking for, unfortunately it seems that it has been abandoned.
