Not many straightforwardly positive comments here so far, so I will write one.
I'm a Firefox user but I've recently been tempted by Arc primarily because of its 'workspaces' feature and its minimal UI that gets out the way. I used Arc for several weeks and really got a taste for these features, so I'm really happy to see them come to a Gecko-based browser. Thank you, and keep it up!
My advice would be: don't advertise wooly claims about performance and security, when it's not clear exactly what's different from Firefox there. Instead, focus on this simple fact: it's an alternative UI for Firefox-based browsing, and that's great.
