I've been in deep thought about this question ever since I saw this thread yesterday. It's been all I can think about. I've gone back through most of the major TMO threads and rated users based on willingness to help as well as depth of knowledge. I've consulted friends and family members, and even had a chance to organize an independent think tank consisting of some of the industry's top minds. They employed the use of sophisticated algorithms in combination with advanced AI developed solely for the purpose of answering this question.

Strangely enough, all efforts indicate a statistical tie between two TMO members: vi_ and abill_uk.

I personally cast my vote for abill_uk because his exhaustive knowledge of USB port engineering and design pretty much revolutionized this community and showed the world what was possible in terms of USB port troubleshooting.

If I were more of a software person, I would have voted for vi_ because the code in his signature has done so much to help so many.
