If I've already been using Arc for a long time, is there any benefit of moving to Zen? Active development, I suppose?
It's open source, and it's not part of the Chromium monopoly threatening the open web. As a direct result of that, you still have uBlock working without any compromises.
So I also use and love Zen. That being said, the "every window's tab list is kept in sync" feature they introduced is... odd and really annoying imo.
Was a big fan of Zen. Alas! Lack of compat with Google workspace (eg sharing audio for a single tab on meet) meant it did not stick.
