Singles Gold > Doubles Gold
Doubles Gold + Singles Silver > Singles Gold
So in Olympics:
Murray > Federer > Nadal.
Beg to dissagree, I bet federer would rather have the singles gold olympic medal rather than a doubles gold and singles silver. Same as in Tennis he rather wins another singles slam rather than winning two doubles slams. His single career is what matters to keep being in goat status. His doubles gold only matters for switzerland and patriotism, but the top atp single players couldnt care the less about doubles championships (wether atp tournamers, olympics,etc) achievements..
In paper its better the Fed case, for olympias medal table, winning an extra gold in doubles and silver in singles. But for tennis career and personal achievements the singles gold will always have the edge when he has to give his career winning resume.
For tennis career: ( reasoning singles careers is what matters, doubles doesnt mean anything)
Nadal = Murray > Federer
For the olympic medal table, patriotism and country: (reasoning a medal is a medal)
Murray = Federer > Nadal
I bet Feds cares more of his personal tennis career than what makes switzerland happy for a couple of weeks...
