Opinions on Diet Coke

Every time I see someone say that they drink diet soda or know someone that drinks diet soda there's a bunch of responses along the lines of, "Might as well drink normal soda!" and talk about how bad it is for you.
My question is, why is it as bad as normal soda? I'm confused, I thought that the whole point was to cut out 100+ calories from your day well still having something sweet to drink?
Opinions from either side are appreciated.

It's better because it has no calories. It's worse because the ingredients can be shady.

Artificial sweeterners and carbonation are both bad for your health

a way better alternative than regular soda, m8

drink only water and milk faggot

Never seen a thin person drink diet coke.

its fine but the ingredients that make it no calories are not as good as just drinking water and coffee with no cream/sugar of course

That's no way to live

fat fuck

hedonists aren't welcome here
