Anecdotally, the niche it solved for me for a while was "Safari for optimal performance on mac, but with proper extensions like ublock".
I used it regularly for almost a year, eventually got off because of some UI bugs that came up and because the Safari dev tools feel so clunky/need relearning compared to Chrome & FF.
