I think it's important to note that much (all?) of PARCs research has been oriented around the "office of the future". In the broadest sense of that vision, they had a huge hand in originating a lot of computing technologies.
And while SRI has had their impact in the computing industry, they also have other research labs that have very little to do with computing such as biomedical, education, and policy.
