I'm using Orion as my daily driver on iOS mainly because of a Safari bug[1]. It used to be very buggy, had frequent app crashes for no reason at all but nowadays (since a year?) works pretty fine, even the UBO plugin works fine.

1: You can long tap and select "Download Linked File" on any link in Safari, including links that are forbidden by Content Restrictions, such as a news.ycombinator.com link from google search. Ping me if a Safari engineer sees this and fixes it!
