True, but a bit of a moot point if both search engines will indiscriminately route you to those websites anyways. It's not like I'm opting-out of that issue by using DuckDuckGo right now.
Yeah, I'm strictly talking about search results. That's the main thing I care about. No ads is nice, but if I can't find information I need then that's not very useful to me.
Not in my experience, and what about user tracking and pervasive advertising? You don't seem to include that in your comparison.
