DDG is actually a hybrid of my own crawling/indexing and BOSS/Bing/others. Additionally, I don't use the others straight up. So for some queries they may look similar and for others they will look completely different.

Wrt to spam sites, DDG often looks a lot different because I maintain a large database of spam sites that I remove from results. I see these crop up all the time in the API feeds I use. It's over 60M in just the main tlds (non country level domains).
