In evaluating Brave, you have to give it apples to apple comparison anyway. Brave vs. Chrome as its directly built on chromium. For compatibility, it shares the chrome app store too. I like to think of Brave as Chrome without most of Google but with all the benefits.
Anecdotally, I switched a colleague to Brave about 3 months ago. He decided to switch back to Chrome. Chrome was so much slower than Brave and added battery drain that he came back. I assume it was all the additional requests cut out (Google) or blocked by Brave (Adblocker).
