at risk of being called a consumer of lewd media, you are aware that google is both obsolete and actually detrimental to finding your desired kind of material when it comes to searching for pornographic materials, right?
even bing would be better.
Bing is better if you're not trying to use an image to find the source of said image or use a thumbnail or screenshot to find a particular video or game. Otherwise you've got to go with Google as Bing doesn't have reverse image search capabilities yet.
What Bing is good at is finding quality videos, imagery and links overall. Plus Bing has a rewards program which pays in gift cards, contest entries and donations to various non-profits, so it's nice if you want a little something extra. It's also easy to check the news on Bing because it's homepage will have links to the top fifteen news stories at the time, updating a couple times a day.
Google however searches for both the high-quality and low-quality to present almost everything there is on a subject. It also has reverse image search services and translation services as well, things that last time I checked Bing doesn't have.
Then you've got DuckDuckGo, which goes beyond and finds everything related to what you search for while not tracking your search history, but at the same time searches too much and thus is even harder to filter through than Google. Privacy is important and sometimes it's very useful to see everything there is on the entire surface internet about a subject.
Essentially if you want quality over quantity, want to stay up to date on the news and maybe want to get a little treat once in a while for doing just about nothing, go with Bing. If you want a mixture of quality and quantity as well as additional functionality, go with Google. If you want quantity over quality and value your privacy, go with DuckDuckGo. Don't even bother with the others right now.
