I recently moved away from datahogger chrome. Google is throwing me captcha every single time I use Brave browser, but same thing does not happen when using Safari browser. Why is that?

I'm guessing 3rd party cookie blocking being on by default.
That's not the problem. Even if you allow them you'll get scrutinized by recaptcha currently. Seems like a fix is on the way though.
User agent string, among orhers, affects how often you get captcha.

For example Tor Browser with default user agent gets all the captchas, many rounds per. Same Tor Browser with manually overriden normal Firefox UA barely gets any captchas.

Brave uses Chrome's user agent string.
Tor Browser uses Firefox UA. Brave browser uses Chrome's UA.
Tor Browser uses one particular Firefox UA, which is very much a give away that you are using Tor Browser.
Tor browser uses the most popular Firefox UA, used by the extended stable version of Firefox, and used by the thousands of people who turn on privacy.resist.fingerprinting.
See upstream thread about a coming fix for this (search on page for “GitHub”).
