I switched to Brave Search and generally am pleased. I did notice current events is somewhat lacking. I was searching one of the wildfires in NM yesterday and no dice. Otherwise for general information or more "static" type info I've been pleased.
Code / stackoverflow is also somewhat lacking on Brave Search, but I'm a big fan of the ability to do !g to redirect the request to Google (I don't care if they see that I'm trying to figure out why my build is failing c: )
I've tried Firefox a few times over the years and always switched back for the same reason - it didn't feel "snappy" and some things didn't render properly. Something has changed recently though. Both these issues appear to be completely gone. And now that I've got the Containers extension installed, it's superior to chromium in all material ways, except maybe the dev tools.
Google - it's a really good search engine, but obviously biased and doesn't care about your privacy. I use it on my work machine.
Brave Search - I'm not sure if another service (like Bing) powers their results, but it works pretty well for my personal use cases.
