Good information gathered and shared. I appreciate it. I have not read anyone do the 135i MC with the F30 brake upgrade. If it's optimal than the M3 MC, I obviously am not qualified to determine, but would be nice to know once this is settled. I am contemplating to do this upgrade soon as I've all the parts except the new MC and would be nice to know which one of them works as intended, coupled with the correct pedal feel. I've yet to overwork my stock ones on track so I'm not in a hurry. Thanks again for sharing your expertise.
I think either the 135 or the 1M master cylinders will do just fine. It's purely a feel thing. The 1M cylinder is also about 4x the cost used and at least double aftermarket. It would feel tighter and more immediate but would have the same feel once pressure is built.

I think the 128i MC is a bit inadequate on take up judging by my first drives.
