I don't like how it looks either. Way too busy. Only thing is, it is lightweight though. New reddit usually crawls to a halt after half an hour of scrolling (which is probably good for my mental health).
I agree it's terrible on mobile, but it's the wall of text I love on desktop. I want to see as many titles on a subreddit as I can.
The Lemmy web desktop UI is quite similar. I just wish the list of subscribed communities was more accessible rather than being at the bottom of the instance home page.
