You're a pro tennis player. You'll have a decent enough career. Mostly a journeyman but with a few notable ATP tournament wins. However, you also get one grand slam singles win. It'd be a fluke in terms of your overall career and the careers of your top contemporaries of the era. But it won't have been a fluke within the tournament itself. For two weeks you'll manage to eke out the greatest tennis of your life. It won't be sustainable given your overall talents, hence only the one grand slam. But the stars will align and you'll miraculously punch above your weight and you'll somehow manage to win it, beating the best in the world fair and square along the way. It'll be a two week adrenaline rush where you actually manage to hold your nerve to the end instead of KWABing right at the final hurdle.

Redpill me on the 4 big titles/bodies
Are they basically all equal in prestige?
Or are some/one more prestigious than the others (the way Wimbledon is seen as the creme de la creme of the tennis grand slams)?
Like, lemme ask you guys as boxing fans, if you were a professional fighter, and you could be world champ, one time (multiple defences, but only one run), and it was only with one of the title...which one would you prefer?

And what do you think about the IBO (the title and the body)?
