14 slams was the previous GS record. Nadal will have 14 slams at the most difficult slam to win.

I agree. Although I believe winning 14 RG titles is harder than winning 14 USO titles, simply because of clay being more taxing to the body than grass or hard. There are way more rallies are played on clay on average.

It’s clearly not harder for Nadal, for him winning the other slams is harder
No, because he is much much better on clay than any other alive/dead mankind on another surface.
On the other hand, the chances of facing an upset is higher on grass/hard. I didn't consider that.
