Energy > Efficiency, Cost, and availability, etc.. considered... "Better" is such a poor spec. If you mean more efficient, even the lamest switcher is much better, and the gap widens as the input voltage rises. For "low noise", a properly bypassed linear would probably be better. Low cost, pretty hard to beat a 7805 -- Feel the power of the dark side!
