Out of the legends it's hard to not say Jay. Not only did he work with a classic run of greats, but he also wasn't afraid to help break new producers. Ski, Clark Kent, DJ Premier, No ID, RZA, Q-Tip, Pete Rock, Kanye West, Just Blaze, 9th Wonder, Timbo, Neptunes, Swizz, B!NK, Eminem, Sean C & LV, Rockwilder, Erik Sermon, 45 King, Puffy, Teddy Riley, Rick Rubin, DJ Quik, Dr. Dre...not too many elite level and/or well known producers he hasn't worked with. He even worked with some greats like Madlib but it's unreleased.
Out of your list, Currensy also always works with really dope producers that compliment his style. Rick Ross has really solid beat selection, as does Game (or at least he did back in the day.) I'd say Busta probably has the most underrated beat selection out of your list. Action Bronson probably has the most overrated. He even tends to pick subpar beats from the best producer he works with (Alchemist).
I'm not that familiar with ASAP Rocky's music. Drake's beat selection isn't really my thing but when he has beats I like I like them a lot. Ludacris is an interesting choice. I guess his is pretty underrated also.
