There are a minimum set of extended functions that I need from a browser that I'm going to use daily. They are: a speed dial that I can manually organize, a quick javascript switcher and an adblocker. Brave has only one of those.
So I'll stick with Chrome/Chromium on my desktops thank you very much. On mobile, Dolphin Browser gives me 2 out of the 3. So, for a long while I did most of my mobile browsing on an 8 inch Windows tablet with full Chrome. Recently I have been trying out an iPad Pro 9.7 to replace that tablet. It's a better device in every way except for the web browsing which is a second rate experience on iOS.
However, I'm thinking of forking Brave for iOS so that I can make it do whatever I want. It's just a wrapper for WkWebView written in Swift. Shouldn't be too hard to alter for my purposes - I might get started this weekend!
