I was just coming to report my experiences with github in Orion with 1Password:
Good news, anecdotally (sample size 2) it doesn't seem any worse off than Safari! On one big PR (143 files, ++8k --2.5K) it still has the classic Webkit "Wait for two seconds while the textarea renders and 1password hooks into it". I really wish either the Webkit folks or Github would do something about their transform-based layout, it runs like hot garbage on non-chromium.
In other hot garbage news, I forgot how smooth Orion's video playback is.. almost looks unnatural compared to Chromium/Arc
