Eternity even though it’s no longer developed it has all the features I want that the others don’t have.

Voyager + Thunder - Don’t have comment navigation with volume buttons.

Summit - Can’t set it to show the content of the collapsed parent comment.

Jerboa - Can’t set a default comment sort, literally have to resort every time you click into comments.

Can’t set a default sort for comments which is absolutely crazy. You have to resort every comment section you click into.
