Uh, No!
It was Hendrix, hands down.
Hendrix was great, no doubt. Even though the crowd was only about 70k strong at that time (who knew hippies had to be at work on Monday?), he lit up the place and gave a great closing performance. It is sad that most of his backing band wasn't mic'd and that that version of his band only played one or two more times.
But perhaps because he was so stoned (and there was also some heavy management stuff going on - watch a presentation by his percussionist Juma Sultan On YouTube), while his playing was electric and he moved and grooved, it wasn't like Monterey where he DID best The Who's live act (though, frankly, Otis Redding stole Monterey).
Don't get me wrong...Jimi is easily in the top 3 at Woodstock (Sly and Ten Years After are also contenders, and Mountain and Santana and Johnny Winter rocked). But I vote for The 'Ooo.
