Here's a tl dr for you on 'why do I need a new browser' from the post: Otherwise Firefox and Brave are excellent and cross-platform. If you want a WebKit browser, Safari with the AdGuard extension blocks ads and trackers, has extensions including more password manager options, and has its own email relay feature.

In my opinion there isn't much reason to use DDG Browser unless you really like the fire button. Plus it uses WebKit so theoretically it should be fast and battery efficient like Safari.

It's a really nice compromise between 'save everything until you delete everything' and 'incognito mode' that I wish other browsers would adopt. That said, it has a cleaner interface than Brave, and it has that fire button from DDG Mobile that deletes everything except for cookies on sites you 'fireproof'. On YouTube, it can't block the ads unless you open in the 'Duck Player' (a page where it embeds the video). My local newspaper's site has grey boxes where the ads would be without content or DNS blocking. It's just blocking common tracking domains and elements, so you don't get (much) cosmetic filtering and some ads will still show up. DDG isn't doing uBO level ad blocking like Brave does.
