KS3 or BM-KS Max?

[doubletheprof]

So I mine via housing platform circlehash, and i own a few KS3M and KS3 from iceriver there, they offer 0.14 USD kW/H for energy, which is quite good, so I dont really mind the high energy consumption of KS3s, but Ive heard, that Bm-KS Max provides more TH/s than KS3s for the same energy consumptions, do you have any experiences with that?
