All good points, but I think overly focusing on things that weren't really unique to Hendrix; pentatonic based riffing and soloing is certainly a staple of rock, but it was Hendrix who popularized things like the wah and octavia pedals, heavy feedback being used as part of the overall atmosphere, theatrical stage presence, and his raw forever improvising-every recording you can find is unique-that sets him apart from the rest. And like I said, pick any of those guys you name and they'll all say the same thing about him.
