TouchdownGreat, write why you think so.IMO Fed is out of question, as soon as some competition came up, he started loosing. So you can't say he had it tougher,because he never won slam beating Nadal and Djokovic at the same tournament. There can be discussion between Nadal and Djokovic. For Nadal strong case is he never had it easy, as soon as Fed started declining,Djokovic came in. But he lost his last final againts Fed in 2017. He was 30/31, Fed was 35/36. Not winning a set against Djokovic on hard since 2013. His only strongforce is clay and he defended it really well but competition on clay in this millennium was laughable (Fed and Nole being his best competition). On the other hand we have Djokovic. Specialised in hard courts, most people play their best tennis on that surface. Had grass court GOAT to compete againts on Wimbledon, had clay court GOAT to compete againts on RG, and on his best surface had biggest competition. As soon as Djokovic came out of story,Fed suddenly ressurected and started winning slams again. As soon as Djokovic returned,Fed stopped winning slams again. Nadal hasn't won AO since 2009, Wimbledon since 2010. I only assume that you couldn't differentiate between toughest competition and toughest slams won, as both Nadal and Federer didn't win that much after Djokovic came in in 2011.
