In my workplace qwant is the default SE and I'm sorry to say it, but its awful. Maybe if you search in French it will be a bit better.

I'm using DDG and I'm quite happy about it. Very rarely I switch to google and if I do it usualy to search some location specific things like nearest pharmacy.

I can’t stand their key: "&"

"!" I can easily type just with my left hand, "&" requires left & right hand working together. For something, I use as often as bangs on DDG that is simply not acceptable.
