Re: Which would you rather have? Career Slam or 5 titles of the same slam?
Five of the same GS. It means you've been a GS champion for five years. A 'Career Slam' can be accomplished in one year. To me, someone can win 30+ clay court titles and show that they're one of the greatest on clay, despite not winning a French Open. That's just my two cents.
Just two active players have won more than 30 titles in their career, so your number is somewhat questionable. Moreover, I didn't notice anyone talking about Anabel Medina Garrigues as one of the "greats" of women's tennis even on clay despite her fitting your criteria the best. So, either you're seeing AMG as the best clay court player of XXI century behind Henin or simply you've lost the plot.
