G Unit would wash the Lox.
G-Unit's catalog is more known thanks to 50 but Verzuz is about performance and Jada proved it twice already, Ross proved it against 2Chainz etc. If one party takes a verzuz as a battle then it has the edge even if its catalog is inferior.
Honestly, I thought Dipset would be close but the gap was ultimately huge because of that. If 50 or Banks half asses their verses and don't bring the energy, they will lose the verzuz. Song for song, G-Unit is superior but the performances and showmanship matter more in that setting.
