Luffy's personality has effectively changed. He's jollyer and more cheerful because of awakening. The ID guards likely got dumber because of their simple animal awakenings. Kaido, Luffy, Sengoku, etc all have mythical "god" zoans. If they have awakening, its not remotely comparable to simple animals coming out when awakened.
It's STILL the same user, but that doesn't imply there isn't a soul in the zoan. The Gorosei literally say that's the case here.
