I like the standard UI. However, if it is inevitable that the site switches, I do prefer this Alexandrite UI. The Photon UI seems much more clunky. And my ADHD has trouble focusing. I do notice that it does allow you to easily look at users’ post history, which is good for moderation, but Alexandrite feels like it has more user related features. I even tried to go into Photon’s settings and tweaking the front page. Nothing I did felt really as comfortable as the Alexandrite UI. My vote is here.
