I personally think you can do alot more with cod edits simply because of the more interesting animations, more customizable cams and death anims, and the fact that you spray and ads more in cod whereas in csgo you mainly go for one taps and short bursts which makes the edit seem slow and dull
mainly it's how creative u are but cod is just better because it's more flexible and animations are way better, csgo was designed as a competitive game so it's not meant to look as realistic/cinematic
