It's important to lend some perspective to the OP's facts -
Fed did well from the aspect that he didn't end up like a Coria or someone else after a crushing loss,completely GONE. Instead, he kept going deep and whenever the opportunity presented itself, took it with both hands(the exception being USO 09 which was his own carelessness). This is certainly creditable and speaks volumes about his character that he won slams even after those crushing losses, maybe other players would've put their hand up and just given up. A big reason for this is that Fed's always felt deep down that if he's playing at about 80-90% of his peak level, he can beat anyone on any surface except Nadal on a slow high bouncing surface like clay/slow HC.
That being said you also have to acknowledge that he didn't beat Nadal in any of those 5 slams he won since his 08 year given that Nadal's been his main rival since I'd say 06/07. Now does this delegitimize those slams? Absolutely not. But that begs the question, did he fully recover from those crushing losses and did he infact get back on top? Did he conquer ALL his challenges and his mental demons? It's not completely clear.
For me the big point of contention was how Fed played the AO 09 final. He had chances to put away Nadal in that third set but just couldn't break him when it mattered. It's not so much the fact that he lost, but the manner in which he lost and the way he had reacted to his crushing loss of the Wimbledon 08 final which reared its ugly head in the 09 final. I fully appreciate the fact that Ralph is a terrible matchup for Fed and with the high bouncing slow surfaces and heavy balls it makes it even harder for him. But Fed's body language against Nadal is what is unsettling. When he falls behind, his shoulders drop, his face has a look of resignation which is quite frankly not the mark of an indomitable champion. Fed doesn't play Nadal on his own terms, rather he waits for Nadal to crumble(which almost never happens), this is perfectly epitomised by his BP % against Nadal which is borderline abysmal.
I've always felt Nadal is Fed's Achilles heel and that hasn't changed since they first met back in 04. So to summarise, I think Fed would take those 5 slams and feel he did well for himself given what he went through in 08 but he may feel conflicted that he couldn't conquer the challenge posed by Nadal especially when he had the chance to set the record straight in the AO 09 final which may make him feel less invincible.
