JoeyKeys V1 - People have been using name disses against Gasmasq for years now, it's really not clever anymore. Lost to Rav and MadFlex is decent, mayor diss is funny, album diss is much heavier. Drawings diss is decent, philosopher diss is okay.
Gasmasq V1 - Opticals flip is consistent with Keys' finisher. Didn't win until afterward is good, broken flow flip is alright, didn't save you an album / domain flip is awesome. Jaw's wired shut is strong, PiGPEN flip is awesome. Producer diss is decent but a little off-beat.
JoeyKeys V2 - Flow gets worse since last time. Google diss is decent. Same flow since 2005 is okay. Doubletime is bad.
Gasmasq V2 - Interruption line is solid, doubletime flip. Google flip is solid, compliment for both verses is nice. Last several bars are mediocre.
Both of the first verses are the best in the battle. Joey uses a lot of punches but doesn't put enough sting into them. Gasmasq matches the punches with flips of equal quantity and greater quality. Joey doesn't respond with enough flips and even Gas' mediocre second verse is enough to give him the win.
