I agree!
When it was said and done. Conor was only good vs much smaller fighters. Meanwhile Lee Muarry was a scary tall guy with long limbs and big bones. So he had an intimidating frame + a solid background story to add to his lore which includes toppling big dudes like Tito.
Conor was a good trash talker/motivational speaker early on and he really struck gold with Aldo fight both psychologically and in-cage performance. Aside from that, he oversold himself in the long run and was not as good as his boastful words. Also his voice and Vince McMahon walk was too silly to be taken seriously as a scary person. More like an annoying pest.
Outside reputation, Lee was known for fighting multiple dudes and did not mind getting stabbed or hurt. Conor had to gather an entourage for protection before acting a fool. Also he called out a big YouTuber saying he could take him in a fight and challenged him. The big dude has meh boxing skills but accepted and Conor ghosted.
In a real fight, Lee would end Conor. Hell, there are tons of guys Lee smashed that would beat the shit out of Conor.
