I'll vouch for that when it comes to beer. It's not just the packaging itself though, but also the experience. Plus, when you drink from a can directly, your lips will touch the outside / top aluminium, which will affect the flavor and experience - subtly, but it's there.

Ahhh the subtle flavours of rat shit. I've never seen someone wash the top of a can before opening it. I mean, would you go around licking random surfaces that other hands have touched, rodents have scurried over and defecated on, etc?
As an aside, to me Coke from can has a different feel from Coke from plastic bottle. Almost as if the bubbles are fewer and larger when sipping from a can.
Mexican Coke, which uses cane sugar, comes in a glass bottle, but you can also get US coke presumably with corn syrup in a glass bottle and some people do think it tastes better.
Though, it is complicated because there are multiple bottlers making multiple different coke products, and even the same bottlers could shift what sweeteners they use over time, presumably based on pricing.
I prefer glass bottles for my beers.
