Chromium vs Brave

This might have been discussed to death by now, unfortunately I couldn't find any discussion on it on Lemmy. Though I would love to be corrected on that!

How does an always on incognito Chromium with uBlock Origin on medium mode (and other hardening/privacy settings enabled) compare to Brave (with e.g. Privacy Guides' recommended settings) with respect to security and privacy on Linux^[1]?

Commonly heard whataboutisms:

• "With the looming advent of Manifest v3, this discussion might not be very relevant for long." I'm aware.
• "Just use Firefox/Librewolf or any other privacy-conscious browser that isn't Chromium-based." I already do, but some websites/platforms don't play nice on non-Chromium-based browsers due to Google's monopoly on the web. Sometimes I can afford to not use that website/platform, but unfortunately not always.
• "Brave's [insert controversy] makes them unreliable to take services from." Honestly, I think that if both solutions are as effective that a reason like this might be sufficient to tip the balance in favor of one. Because ultimately this all comes down to trust.
• "Just use Ungoogled Chromium." Some more knowledgeable people than me advice against it. Though, I'd say I'm open to hear different opinions on this as long as they're somewhat sophisticated.
• "Just use [insert another Chromium-based browser]." If it has merits beyond Brave and Chromium with respect to security and privacy, I'll consider it.

Thanks in advance!

1. I can be more specific about which distro I prefer using, but I don't think it matters. I might be wrong though*.
