Coke Zero is good shit and it's as close to the real taste of any diet drinks. I gave up diet sodas about a year ago and will on occasion grab a Pepsi or Coke when I need a jolt. My teeth feel like they have sweaters on after I drink them though.
Salted caramel sounds horrible though for a soda flavor.
Yeah, I actually did a thread on here about when I gave up diet sodas. Instead I will just have an occasional regular soda. And I agree with you about the teeth feeling. For the last week of the year, I've just been going hogwild, so I've been having a 20 oz soda everyday.
Maybe my perception is clouded by the mango pepsi that was released a few years ago. I don't like mangoes and I would never seek out a mango anything, but in a special edition pepsi, it was pretty good. I'm on the adventurous side when it comes to trying food, so when a special edition version of a product I like is released, I have to try it.
