Northern Illinois checking in. It’s pop.

Michigander here - Pop.

I say soda. I feel it’s about split 50/50 in my local area

Strangely, Decatur, IL is in the “soda” region, but my family usually says, “pop.” I knew a guy from Peoria that said “sodie,” no idea if that was regional or just him.

Soda, always and forever. (I even converted friends and my spouse from “pop.”)
