My experience with Arc was installing it, asking myself "I have to pay to change the app icon? wtf" and uninstalling it. Horrendous UI as well.

Personally I liked the UI (and now use Zen browser, the UI is very much a matter of taste though), but left as the browser itself kept getting worse

That's very interesting. I downloaded arc because I saw it in some twitter screenshot and I thought the UI was neat, when I could have actually been looking for Zed instead of Arc.
