id sign to mmg to hang out and listen to beat with rick ross in the studio and soak up game/connections for when i eventually gotta go out on my own
i feel like alot of those other labels are good, (or i dont know much about them) but are too saturated with other artists you might get overshadowed by.
i feel like with MMG at least, you can pick up some jewels and some $$ to keep you movin forward if you're about your business
roc nation might be a close second
