Faster iPhone charging through a MacBook?

Is it true the iPhone charges fastest through a MacBook? My friend says the MacBook throws more power at the USB socket when it detects an iPhone, and that it's faster than a standard charger? True, or an urban iPhone legend?

Not sure if it's true or not, but I charge from the USB port on my MBP, the iPhone charger and my iPad charger. It charges quickest if I use my iPad charger which is the majority of the time as that's the one I leave plugged into the wall all the time. From using the iPhone charger and USB I think the charger seems to be slightly quicker from what I've noticed although not dramatically so.

I guess you could run your iPhone down to 0% and do a test using both and see which charges it quicker if you want to be exact and see which is the case.

From Apple:
USB 1.1 or USB 2 ports:
Up to 500 mA (Milliamps) at 5 V (Volts) to most Apple USB peripherals and all USB peripherals not made by Apple in compliance with USB specifications.
Apple computers with USB 3 ports provide:
USB 3 ports:
Up to 900 mA (milliamps) at 5 V (Volts) to most Apple USB peripherals and all USB peripherals not made by Apple in compliance with USB specifications.

Meaning it will be faster if plugged into a USB 3 socket, but from the looks of it not as fast as a dedicated iPad charger which is around 2000 mA ( 2 amps)

I find iPhones (5, 5c and 5s in particular) charge faster through a Macbook. But not significantly. They charge pretty quickly, anyways. i find my BH's iPad 2 charges faster through the iPad charger than when connected to a Mac.
