If you give me three Slams with option one, with Fed winning 1 more AO, 1 more Wimbledon and 1 more US Open, in 3 different years, than I'd pick that one.
12 slam winning years
+ he'll play at least 3 more years for me to enjoy him.
With the two slams, I don't see it being hard. I pick option 2 anyday.
