As Finn I rarely search for Finnish specific stuff. Sometimes I check prices or if something ships here or not, but that is exceedingly rare and for that DDG works fine.

As for bangs, I love skipping clicks. Most of the time I know what I want and can use bangs accordingly. I'm guessing my most common tags are !a, !yt, !gh, !wiki, !wolf and then some game(s) specific bangs.
