Stochastic Frontier Analysis (SFA) or Data Envelopment Analysis (DEA)

#1
I'm trying to analyze bank efficiencies and come across two of the most used method of efficiencies measurement. I've studied many published papers on SFA and find some simplicity of the data that have to be used to run the method on statistical software. I wonder if anyone could enlighten me on DEA and are there and advantage or disadvantage on choosing one measurement or another
