I’ve been using the Arc browser for two months now and I’ve come to really like it. It was hard to move away from bookmarks at first but there are so many little nice things in Arc that make it really pleasant to use. I didn’t even plan to move away from Brave which I also really liked, but I have not gone back yet (only on mobile since there is only an iOS version right now, no Android). They have this feature where it asks you to make Arc your default browser for a week. Without that I would never have given it a chance for more than a few hours, really great idea.
