Worst issue with plastic containers f9r soda is taste
The slick plastic bottles have an impact on taste especiallly in heat
Rough plastic and aluminum not so much and glass has the least impact of anything on taste
My opinion
If you’re sixty you remember when it was glass or steel only
I don't really notice plastic when drinking sodas, but I never drink coffee out of plastic, like those travel mugs. I can't seem to taste coffee when it's in a plastic container. There are metal travel mugs with plastic inserts which also suck. My travel mug is all metal. Don't know if they even make them any more.
