Interesting, I use DDG by default on all my devices and rarely ever miss Google. If I do, it's just a !g away.

Conversely, when I use google, I frequently miss !w (search on Wikipedia), !i (search images), !a (amazon) and other "bang" shortcuts.

You can achieve something similar to bang shortcuts by adding different search engines to your browser of choice and setting short keywords for them.

E.g., in Chrome: Settings > manage search engines > find Wikipedia > change the shortcut to "w."
