Using five technical searches I might actually make on a day by day basis, I chose Google 4 times and a draw once, though the results were close almost every time (once I chose Google because I searched for an organization name and wanted their homepage first rather than relevant news, and twice because the relevant result was from MDN rather than MSDN or W3C since I found that MDN tends to be the best site for actual technical reference, so YMMV).
