I've tried but like all other apps it's not perfect. I don't know why you can't tweak the spacer in your post view. List With Cards gets kinda close but the spacer is too big (and the cards could be a little more compact). With Compact view the spacer is too thin.

I also hate the way it handles user avatars/profile pictures. Why are Sync and Boost the only apps that do it properly? Hide it altogether if no custom picture is selected, otherwise display it. All the "default Lemmy" user avatars make the comment section too busy in Summit, but I want to see custom ones since it helps me identify people I recognise.

Summit also doesn't do a different font colour for pinned threads.
