Arc is the only alternative browser that I actually managed to stick with. I love the small details, the animations, the command palette, and how easy it is to navigate through tabs. I also enjoy how clutter-free it feels, even when I have a million tabs open. Since it's a relatively new product, there are more bugs than with other established browser, and a few more limitations in terms of add-ons. Still, I see the team constantly shipping updates, so that's good!
