I could argue why The Who isn't great, but there's no reason. Glad you like them.Fair enough.
Some of my hierarchy is down to the roles these bands played in the development of my musical taste/vocabulary/judgement. Once I started really digging into music on my own terms, I was drawn to stuff that had a certain level of aggression. The Who were often a lot more bombastic than the Stones. And Townshend's lyrics appealed pretty deeply to my nerdy, bookish side.
As I noted, the Stones have a deep catalog of amazing songs. Much love for plenty of their output, at least through the early 80's. But...they also have hung around long enough to put out a lot of pretty "meh" stuff. The Who's post-Keith Moon output is mostly "meh", too. But there's not nearly as much of it, compared to the Stones.
For years my favorite Genesis song I would hear on the radio was Eminence Front. Then one day I found out the truth.
