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.
