Just how good is the 20/1.7?

Uncle Frank's portraits, color & B&W, show the 20/1.7 is just as good for portraiture as the 25/1.4 as long on you don't get in too close and have resultant facial distortion.  Bottom line:  Both these lenses, the P 20/1.7 "pancake" sans syrup    , and the PL 25/1.4, are both excellent.  You can't go wrong with either--or both.  Whichever floats one's boat and assuages one's bank account.
