Federer in his prime >>>>> Djokovic in his prime
Roger started losing just because he got too old. when he was younger he almost always won Djokovic.
besides, compare how much stronger the competition was when Federer dominated - Roddick, Agassi, Nalbandian, Hewitt, Davydenko, Safin, Carlos Ferrero
and what do we see today? Dimitrov? Tsitsipas? Thiem? Zverev? Medvedev? Kyrgios? these guys are literally nothing and their tennis level is awful
and I'm not a fan of Federer, but it's just a fact he's GOAT
