Critical reception
Big Gucci Sosa received mixed reviews from critics. David Drake of Pitchfork described the mixtape as "parachuting Keef verses into the one-dimensional pulp-gangster formula that’s been Gucci Mane’s collaborative stock in trade since 2011," but praised the mixtape's production and Chief Keef's rapping. Matt Moretti of Buffablog described Gucci Mane as "the trap legend," but called Chief Keef's rapping "less than perfect," rating the album a B.
