i hate regional-isms of sodas, personally i love faygo (yes juggalo but honest just enjoy lol) and mr. pibb
living in long island good luck finding. dollar store got (super limited editions of) faygo but i use to always get mr. pibb when i was in college in new england lmao.
when it comes to coke vs pepsi i never honestly had a fav, it was a mood thing cus my mom was the same and i grew up under that lmao.
