You can set up a keyword search for DDG (for example ddg or just d) and use that when you want to compare. In Chrome, Firefox or Opera just right click in search form and select something along the lines of creating new search, and fill out the keyword.
I have a search keyword even for Google (g), my default search engine is "Feeling Lucky". Other keywords I use are (y)outube, wolfram(a)lpha, google (i)mages, t(orrentz), (m)aps (not google), (r)eddit (not a search per-se, just for opening subreddits), and a few others. For wikipedia, imdb, documentations, .. the feeling lucky is enough.
Yes, you can. But you have to think about it, and put a little bit of effort into it, at a moment you really want to do a quick search.
It makes switching a step with some friction, instead of making it possible to 'ease into it' by simply starting to do some search with ddg quickly.
(Heh, notice that many people in this forum write ddg for duckduckgo? I just made two typos typing that in. It's rather unlikely this is not costing them badly).
