More Pros of electric are: A. it will almost always move and mix more water volume per hour than windmill i.e. stronger mixing, B. electric compressors are almost always easier, more convenient to maintain, repair, C. Electric compressors usually require less inspection and few repairs compared to windmills. I find electric compressors cheaper to repair than windmills.
The deeper a diffuser is in a pond the more wind speed it takes to create enough pressure and get a diffuser operating. Thus a diffuser at 5 ft will operate in a much slower wind speed compared to that same diffuser placed at 10'-12' & then 14ft deep.
Some of the newer style electric compressors have more efficient motors and operate more hours per kw of electricity.
