Think about what OP said here for a second:
>every time I can’t find something I switch to Google and find the answer right away
If you assume both Google and Bing to be similarly good but not the same, then you would expect this to happen.
Say there are two sets of websites, the ones that Bing finds (B+) and some that it doesn't (B-).
The same would hold for Google, there would be G+ and G-.
Now if you search on Bing first, and find what you need, you stop. This is a result in B+.
If you don't find it, your result is in B-. Then you search in Google and maybe get a G+ result, since they have different sets of websites they find.
You might also not find it (G-) but in the end both search engines aren't that bad, so this rarely happens.
Now you might find the same result if you start on Google instead, and aren't lucky in the first go, and then try Bing.

Every time I stumble in to google I am appalled at how bad the UX is.
