It's still worth trying and using. The developers consider it a "finished product" and I don't disagree. It does lots of small things well* that many browsers (even the self-confessed clones like Zen) don't do out of the box, if at all. Maybe in two years the browser will no longer be distributed or receive Chromium updates, but it exists and works fine now.

* For example, I get a lot of value from renaming my tabs and even replacing their favicons with emojis of my choice. Zen appears to have limited support for this.
