There is some element of truth in what you have heard. The problem with the A320 is not the brakes themselves, which are excellent, but with the autobrakes which are invariably used for landing. The problem lies in the fact that there are only 3 settings. MAX is used for take-off in case of a high speed abort and is not recommended for landing as it would do unspeakable things to both brake temperatures and most of the occupants of the aircraft! The only 2 options left are MED and LOW. LOW takes 4 seconds to operate after touchdown and just never quite seems to come to your aid in time and MED is a bit fierce. The problem lies in there not being an interim setting to satisfy the more discerning user!
I am given to understand that the 737 has 4 settings and thereby effectively overcomes the problem the A320 has. I think most of my fellow A320 colleagues would agree with this analysis but I shall wait to see if other contributors agree or not.
