Federer has 18 slams out of 69 entered, Nadal has 15 slams out of 49 entered. That's explained by the combination of their respective ages and also Nadal missing several slams all over the years due to injuries. Not trying to start anything but they are pretty even when you consider that fact. Federer has a little more slams, but it's very normal because he's played much more.
