Well I do like new Reddit. It has a dark mode and works well with different screen/window sizes. Sadly it’s slow and equires JS to load the content (makes it slow).

Imo Lemmy web is most of the good parts of old Reddit and some of good parts of new Reddit. Though it’s not the best UI. My favorite UI for Reddit is Redlib [1]. It’s fast, works well on desktop and mobile, and looks great imo.
