Khan The Best @ 147? Comeback More Impressive Than Spence And Crawford Last Fights?

With opponents roughly around the same level in their last fights, is it fair to say that Khan's recent performance against Lo Greco, a 39 second annihilation, was more impressive than the other top tier welterweights last performances - Spence vs Ocampo, Crawford vs Horn? Does Khan now sit at the top of 147 straight away, after 2 years out of the pro ring? Bearing in mind also that Lo Greco tried to gain an additional advantage over Khan by only agreeing to fight at a catchweight above 147, yet Khan still blitzed him easier than Spence dealt with limited Ocampo and Crawford dealt with the limited Horn! Furthermore, Spence needed 3 rounds to stop a Lo Greco who took that fight on very short notice and had nowhere near the amount of time he had to prepare against Khan! All things considered, after being avoided by Mayweather, Pacquiao, Bradley, Marquez and Broner over the course of a number of years campaigning at the division, is Amir Khan now officially the very best at 147 all over again?
