Not a fair contest.
It takes Dr. Hawking a week to respond to questions, due to the fact he has to "blink" (yes, literally blink out his answers)it out, then have it translated in the robot voice.
His body is gone, but his brain is all there.
Einstein had government money thrown at him with wreckless abandon.
Hawking by a longshot, just based on having to be a theoretical physicist while he drooled on himself, when (Dr. Einstein) had everything handed to him from the US government, with a properly functioning nervous system.
Just my humble opinion, of course.
(I just wish Dr. Hawkings robot voice had a Brit accent, it's only right. Too many morons think he is American)
