I've been using Neeva.com for a bit now and I really like it's format and all. It's subscription based, but there's also a free version. They claim to be private and show no ads no matter which service version you're on. Subscription model is $5 a month and it also gets you the premium versions of Bitdefender VPN and Lastpass

I don't think there's a reverse image search and search results by themselves are annoying, but at least they'll allow you to block results and prefer results from news outlets, so at least there's that.

they're always adding features so there's hope that they get better
