Advantage of BK 9918 over MGM120?

Even on 7 cells (haven't tried 6) there is no cogging on my 12012-3s. It also runs my novak motor just as nice as my feigao. So not only does the mgm work for larger scale models, it works for most other applications as well. I think all mgms are smaller than all the warriors also.
