Can someone help me choose between Brave and Firefox?

This is a bit off topic but I feel like I need to choose between Firefox and Brave. I don't like Brave's CEO, but Firefox's UI has to be manually configured to look good to me, while Braves's looks good out of the box. Brave is infested with crypto, and firefox has to be configured to import passwords. I really like Mozilla as a company and I strongly wouldn't like a chromium monopoly but I feel like that fate isn't my problem. Can someone help me decide?
