Overrated and underrated rappers of the 90s

My kid got me thinking about this. Who were underrated and overrated rappers from the 90s (and even creeping into the early ‘00s)?

I didn’t have an my good answers for her for either side of the equation. And I’m thinking of those who achieved some commercial success (rightly or wrongly) not underground guys. Kinda feel most were pretty appropriately rated.
