I think its gonna boil down to your own preference and which ones you want on which bike. Just know the BBs are not compatible so you would have to remove the BB off the complete kilo and get the appropriate bb (103mm) for the RDs you already have. Question is are you willing to go through the trouble of swapping if both cranksets are equal in quality?? That's up to you and that's what everyone is here telling you that you need to make that decision yourself.
