ant man and Guardians of the galaxy are the 2 of my favorites in the MCU. These 2 are funny, and when I come to the cinema, I am expecting lots of laughs that my stomach would hurt. While Ant man 3 was just average (I do not laugh hard enough also), GotG Vol 3 exceeds every expectation that I have. Lots of funny moments, funny arguments between the group, how the members took back whatever they said in within 3 seconds after they said it, and mostly a great character development.
Nebula and Mantis are really taking the show from the original gang, they make a great comedy couple that I would have never expected after watching them in the 2 previous movies + other movie appearances.
Both me and my wife shed our tears on some moments (no spoiler here). Action, videography, CG effects, and everything, GotG 3 is great in every aspect.
