For me the spaces organization, and how they handle tabs is really nice. Cleaning up open tabs every night (being keeping the archive if you need to re-find) is nice, and moving certain tabs up to the favorites area that are long-lived is nice. There's nothing super major that changes for me, but if you're the type of person that collects tabs and then doesn't do a great job organizing them, it could be really nice.
