Fairly sure it's been covered before but I just wanted to say that I've recently changed out the front brake master cylinder and the difference is substantial.
Horrified by the price of Brembo aftermarket units, I fitted a 16mm R1 radial master cylinder from the 2004-06 model. I believe the R6 master cylinder from 2008 onwards are virtually the same and are also a relatively straight fit. Costs around the ton and worth considering if your bike is soon due for a master cylinder rebuild / refurb.
Braking is always a subjective thing but I have to say that there's a lot less effort required to build stopping power towards max....yet somehow the sensitivity is still there, certainly enough to avoid overloading the forks / locking the front up.
