I think All Along The Watchtower takes the cake on this one (and not just because I posted it).
Song that is strongly associated with Jimi Hendrix (no one thinks of Bob), but written and performed first by a music legend (Bob Dylan).
Jimi > Van Halen
Bob > The Kinks

Looks like the level of esoteric connection is on your side; but the overall popularity is on the other side. But popularity isn't everything; as it is 100% clear that your two major arguments are true a priori.
So I'm forced to agree.
