“There are countless examples of great people who were subservient to their Rebbeim, whom they considered to be great, despite a superiority in Torah knowledge and/or learning abilities.”
I’m not sure if you are trying to say that they were greater then their Rebbeim or that there Rebbeim were greater then them. If the latter, what’s your point? If the former, can you please provide an example of someone who had Torah knowledge superior to his Rebbe and was subservient to this Rebbe?
