Stock Chromium (which Brave mostly is, UI wise) is snappier, and has things like tab groups which are amazing. I don't remember the last time Firefox introduced a new UI thing that made the browser nicer to use. Containers, probably? The browsing experience on a mostly stock Chromium doesn't differ much from Firefox apart from containers vs. separate profiles, tab groups and sheer speed. Edge and Vivaldi have a ton of actually novel UI innovations built in. Microsoft's doing a lot of menus as floating panels that can be pinned, which turns the menu into a sidebar. Very normie-friendly but powerful. They also have vertical tabs and can hide the titlebar if they are in use. If they weren't a privacy disaster, they'd probably be just the best browser on the market. Vivaldi goes more the tweaker way, their tab strip is an inhouse custom implementation and they have settings for just about everything. They have three different tab group setups alone, can slap tabs on any edge of the window you want or do away with them entirely, etc. I think mobile is where the bigger differences are: Mobile Chromium browsers have tab groups, and tab groups are just as awesome on mobile. They're also clearly snappier than mobile Firefox IME. Stock Chrome falls behind because it doesn't have any adblocking ability on mobile and no extension support. Most forks do, with varying degrees of power. > Does Brave still do that ad replacement thing? Replacement is a bit of a wrong word, in that it implies putting their own ads in place of the normal, usually evil ones. Brave has, separately, a traditional ad blocker (built into the browser instead of being an extension, so it doesn't get nerfed by Manifest v3, and can do CNAME uncloaking like uBO on Firefox can) and an ad delivery system that shows ads from a local catalogue as the background in new tab pages and as toaster popups. Both can be toggled off (and the popups are off by default) and their frequency adjusted by the user. If you turn the ad stuff off, it's close to being a stock Chromium with a bunch of tinfoil and a standalone sync infrastructure.
