That's a good question and I don't know the answer. I hope somebody with more experience will chime in.
I installed two circuits in our house that needed to be 20A dedicated circuits. One for a large air compressor and one for a basement sump pump. In both cases the breaker is rated at 20A and the outlet is the T shape. Don't know if that's overkill or not.
Looking at the existing circuits in my breaker box I see a variety of 15 and 20 amp breaker switches with no apparent rhyme or reason as to the rating. All the other circuits (except the dedicated circuits) serve a variety of wall outlets and ceiling lights.
Back to the 15A outlets common in most houses. There are usually several outlets on the same circuit. You can't really draw 15A from every outlet.
