I check in with Orion from time to time, definitely getting better. The only thing that stops me from making it my daily driver is that 1Password support is still absolutely terrible. I hope that gets fixed soon, it's a good browser.
I like it a lot. My main annoyance is when you have tons of bookmarks like I do the list freaks out and takes a good 5 seconds to fix itself. They're doing great work though, can't be easy trying to maintain parity with Safari while adding web extension support.
