Bangs can be used anywhere in the string. I use them at the end so if I want to try another source I can just update "searchingthis !mq" with "searchingthis !gm". No need to go to the front of the query and update the keyword there. Also, you don't have to configure anything. DDG bangs are intuitive. I find myself searching sites I wouldn't have otherwise.
