I love them all tbh. Chocolate milk is what I voted for but I love all kinds, I love malted milk, strawberry, banana, vanilla, and plain too. Milk is just so freaking good. That's why I can't be vegan, it's just too good.
Chocolate milk is pretty great, so I think I'll give my vote to that. I also remember enjoying vanilla milk when I was a kid, but I think the brand I had stopped selling it or something and I haven't had it in years.
I've actually never had banana milk or strawberry milk, so I'd have to try those before ranking them. Plain milk is fine too, but it doesn't really compare to flavored milk.
normal milk...., chocolate milk is rly gross, never tried any of the other but they dont sound good either. if i want milk w/ something i'd have a glass of normal milk and i'd drink normal milk and eat a straeberry or w/e with it
