I recently switched over to Brave on Android after Firefox just got too annoying - frequent crashes, excessive reloading of pages, just feeling bloated, and lacking the fine controls that I make strong use of on the desktop. And so far I'm impressed. It is significantly faster. I mean actually, noticably faster on all my regular websites. It does not have excess bloat, yet seems to have everything that I need. So they have a happy customer in me.
I will check out Brave Search when it comes out of Beta, as I'm finding DuckDuckGo is getting less and less helpful with results. Here's hoping it works out well for Brave...
