its just a matter of oppinion
okay so tsonga made a slam final and won a masters title. Its not like david has never made a masters final
and okay so he never made a grand slam final but how many people are actually going to remember tsonga the slam finalist when he's not playing anymore? there's really not much to choose from between the two at this point
There are far more reasons why Tsonga will be remembered though:
- Beating Federer at Wimbledon
- First player to ever beat Federer in a GS from 2 sets to love down
- Beaten every top 4 player in a GS
Hell, he might even be more remembered for that performance against Nadal at the Australian Open a few years ago, one of the greatest performances ever surely.
