I like it
Been using the browser as a secondary one for months and it's become increasingly stable. Internally it's also running on Chromium so site compatibility isn't a problem.
I suspect it will become my main browser before the end of the year and I've come to the conclusion that I'd even pay an annual fee for a good browser and mail client.
The developers, many of which are ex-Opera, are extremely open to usability in a way that the major browser have lost. Opera really lost its way when it (thoroughly understandably) jumped on the Chromium ship and had to reinvent bookmarks having thought them irrelevant. It's now got a more coherent strategy that laudably focusses on third-world accessibility but for the rest seems to be chasing rainbows.
