Well Baker wasn’t as influential because for the most part he abandoned rock in favor of African music and Jazz.
That was a conscious decision by Townshend, and while he will always be regarded in a special way vs Page, Page was more influential as a guitarist (notwithstanding how many people trash their gear).
Similarly, Baker consciously turned away from the roar of the crowd (he also has more of a drug problem than Pete, though Pete was an alcoholic in the 1970s and finally started drugging again around 1979-1981).
Thus, Baker may not have achieved the level of influence he COULD have, and that MAY have been his choice. But it remains that his influence wasn't as great as some people believe. And of course, his attitude had NOTHING to do with ANY of this.
