> I use Dropbox instead of Drive and Photos.

For the privacy-conscious, Dropbox is saddled with the same pitfalls as Google and Facebook, unfortunately.

> Google Search is hard to replace because of the quality. Bing is ok but not close in quality.

https://disconnect.me/search used to show Google search results, but it looks like Google has blocked it for the time being.

I personally use https://duckduckgo.com/. The quality of results is definitely below Google, but I believe that'll only improve as more people switch to them.
