Tabs are always vertical which is better for todays ultrawide monitors
You have the ability to pin tabs to the sidebar which means that whenever you’re on a particular site (not page!) they’re stored in the same place
Other tabs are ephemeral, they’re open for at most the 24 hours from when you use them, then they get cleaned away
There are separate workspaces; like swappable sidebars that you can use to - for example - keep work and personal tabs separate
The vast majority of commands (going to a tab, getting to settings plus loads more) are access via a Stoplight like global search control
You can “boost” a particular site and change its style sheet to be different colours - this can be handy if you’re a developer and need to be extra careful when working in a production environment.
That’s just the stuff off the top of my head, there is probably more.
