To be fair it goes both ways. I don't understand the hate for it either. Is Brenden Eich an asshat? Maybe, but that doesn't affect how good the browser is or isn't. And the crypto/ad stuff is opt-in. You can leave it off and it is just chromium with a built-in ad blocker.
What else are you going to use if you don't want to use Firefox? Vivaldi is the option suggested the most but that isn't open source. And extensions and codecs are a pain point with Ungoogled Chromium. As far as I'm aware Brave is the best currently available open source chromium-based browsers.
I don't even use it, I use librewolf for the record.
Yup, Brave is my go-to Firefox backup. I need a chromium browser for work to test our product, and it's nice to have something with an ad blocker built in. I use Firefox 99% of the time, but that last 1% goes to Brave.
For the record, have you also tried the Goanna-based Pale Moon web browser, and compared how well it stands to all those other browsers you've actually dug deeper info on?
