Agree with that completely. The Who of My Generation are untouchable. Like The Small Faces they were good at three minute bursts of energy. I find 70's The Who over wrought and pompous. Each to their own though.
I think only Quadrophenia showed certain pomposity, though I still like it. In my opinion, the essence of Who's Next belong more to the late 60's than the 70's. The Who By Numbers is anything but a pompous album. And Who Are You is hard rock with some experimentation, recorded during the height of disco music.
