Lupe is a lot more influential than you might think. A lot of these other emcees such as Wale, Ab Soul and even Drake have referenced him as having impacted them.
Your list was an interesting read. The only thing that matters to me when discussing the best is who is actually the best at rapping(technical skill, concepts, delivery, eclecticism etc) and who the discography to back that claim up. I don't care about popularity, who had their own sneakers, who was most beloved by the cacs who control the mumus industry, etc. I don't care about any of that shyt.
So going by my criteria, Lupe is the best rapper in history to me. And guys like Jay Z, Nas, BIG, Black Thought and Andre 3000 are among the best as well.
You don't have to agree with what I'm saying, but having Lupe as the 37th best rapper ever means we view this entirely differently.
