Dude, it's the same thing.
Its the same.
Any insight as to charging techniques to keep battery performance high? Do you charge it until 100% then unplug, charge it overnight?
It is not the same (if thats what he was asking). The wall gives you double the current of the USB.
Edit: No need to unplug. Just charge it at the end of the day. Try not to ever let it die, until a month or so has gone by. The main thing is to keep the ions moving in the battery.
