I'm especially concerned about it being somehow broken, unwieldy, insecure or privacy-invasive.

Case in point; at times I have to rely on a Chromium-based browser if a website decides to misbehave on a Firefox-based browser. Out of the available options I gravitate towards Brave as it seems like the least bad out of the bunch.

Unfortunately, their RPM-package leaves a lot to be desired and has multiple times just been awful to deal with. So much so that I have been using another Chromium-based browser instead that's available directly from my distro's repos. But..., I would still switch to Brave in an instant if Brave was found in my distro's repos. A quick search on repology.org reveals that an up-to-date Brave is packaged in the AUR (unsurprisingly), Manjaro and Homebrew. I don't feel like changing distros for the sake of a single program, but adding Homebrew to my arsenal of universal package managers doesn't sound that bad. But, not all universal package managers are created equal, therefore I was interested to know how Homebrew fares compared to the others and if it handles the packaging of the browser without blemishing the capabilities of the browser's sandbox.

P.S. I expect people to recommend me Distrobox instead. Don't worry, I have been a staunch user of Distrobox for quite a while now. I have also run Brave through an Arch-distrobox in the past. But due to some concerns I've had, I chose to discontinue this. Btw, its Flatpak package ain't bad either. But unfortunately it's not official, so I choose to not make use of it for that reason.
