I like both, but Infinity War is slightly better for me. I’m a sucker for dark endings, and Endgame did some things I wasn’t the biggest fan of despite the overall movie still being great. Namely, they jumped straight to Professor Hulk without Hulk ever truly shining, I couldn’t get over that Thor was still out of shape and overweight during the finale, and this last one is a personal bias. I loathe when some random, chance thing moves the plot along. So the rat randomly freeing Antman annoys me.
