I don't want to pick either option. I consider them as EQUALLY good. Why there's no option for that?
Olympics is different. For the sake of your own glory, of course Murray's medals considered more valuable. But gold medal is gold medal in Olympics. The same player participated in multiple events except Djokovic, for example. It doesn't really work like GS where doubles events are just stepsons and stepdaughters compared to singles events.
Nole was in doubles also.
