Depends. Dropping USB 5V to 3.3 with a linear throws away 1/3 of the power as heat (67% efficient).

A good switcher can provide 90%+ efficiencies. They can also operate off lower voltages, like 3.7V lithium ion cells supply. 2.5V to 5.5V input range, 3.3V out. I use them in my designs. If you want a specific recommendation, list the specs you need to meet. Analog Devices and TI both have excellent options. Analog Devices has all of Linear Techs IP. Those guys make some amazing parts, especially if you need low noise.

Big thing for LDOs is input ripple rejection. TI's TSP7A family LDO's reject input ripple out past 2 MHz. Analog Devices has a similar (better) part, but it costs 2-3 times as much.
