So, when/if Novak and Rafa meet at FO that will e 10th slam meeting at FO, which is ridiculously too many...
Then we hear explanation that Nadal is too good at FO so that's the reason, while Novak failed to play some matches on other slams (kinda true if you take i of the context)...
So let's see how they play at each slam thought number of wins...
We see Novak as consistent, with almost no differences at slams, he plays great everywhere... Rafa? Well, see for your self... Clay goat, he is...
Just this graph shows who true, overall goat is, and who just can't be...
That's half of the story.

It's true that Nadal was way more consistent on clay than Djokovic was on grass and hard(He missed only 1 time a Djokodal meeting in RG, Djokovic averaged 2.6 in other slams for a grand total of 8).
But it's also true that Djokovic was way more consistent on clay than Nadal was on grass and hard(He missed only 5 time Djokodal meeting in RG, Nadal averaged 6.2 in other slams for a grand total of 18.5).
RG-Skewed Slam H2H are a consequence of both players merit and faults.
