Some 30 years ago, someone challenged me to tell the difference between Pepsi and Coke in a blind taste test. After taking several sips, I could eventually tell that one tasted just a little bit sweeter, more sugary, and the other one tasted just a tiny bit more... "dark" is how I put it at the time. (Note that I was using that word to describe a flavor, not a color. I do not have synesthesia, that's just the best word I could find to describe the subtle taste difference). I guessed that the slightly-sweeter one was Pepsi, and I turned out to be right.
Thing is, since doing that taste comparison where I alternated sips several times between the two, I've consistently been able to tell if a drink was Pepsi or Coke. So while they are very very close, they are distinguishable to some people, if those people have trained their taste buds. (Or at least they were up to about 10 years ago, I don't know if they've changed the flavor in the past decade because I practically quit drinking soda at all once I got serious about maintaining a healthy weight.)
The difference between the two is not that subtle. If I order a Coke at a restaurant and they bring out a Pepsi, I can tell immediate and usually send it back for something else.
I don’t have trained taste buds, but something in Pepsi is off putting to me. Worse is artificial sweeteners, which I think I’m have whatever mutation makes aspartame taste bitter. I could never understand why people like Diet Coke, but it turns out I’m the strange one.
True story: I was once (late 90s, I think) made part of an impromptu taste-test in a 7 Eleven store in Stockholm [1], when a (probably bored) employee grabbed a Coke, a Pepsi and a Dr Pepper and some espresso-size paper cups and made me and some friends close our eyes and try to guess which was which.
I remember being upset since he claimed I failed to even point out Dr Pepper, which I still think is unbelievable since even its smell is super distinctive and way different from a cola.

In switzerland they once did the test on a TV show making people taste beverage of various colors. Most people would say it has the taste of a fruit of the same color while all the beverages had the same mint flavor.
Bottom line: the brain takes a lot of shortcut to allow us to take decisions quickly and is easily fooled. We aren't much better than a tiny LLM model really.

I did something similar with co-workers recently, who didn't believe there is a meaningful difference between brands. I blind-tasted 6 different glasses and got each one right. I got my favorite (Coke) right just by the first smell, I just had to taste to see whether it was diet or not.
Not that this is a skill or anything. Its just that each of the brands I tasted has a strong characteristic flavor to me, and the difference between real sugar and artificially sweetened is also stark. I've been drinking diet versions for ages precisely because the sugary ones are just too sweet for me.
There's a story (true AFAIK, but it's the kind of thing I can easily imagine having been debunked) of Pepsi winning in direct taste-test comparisons against Coca Cola, but only when the test was done with small quantities. Apparently the sweeter taste is initially more appealing, but the slightly less sweet taste holds up better over the course of a whole drink.
"...but the slightly less sweet taste holds up better over the course of a whole drink."
I reckon from experience that's correct. For example, I can't drink Pepsi Max as it's far too sweet (all I taste is sweetness, on its own that's not very appealing).
They’re easy to distinguish and I bet if I tell you how you can do it easily afterward.
Pepsi has more vanilla and lemon. If you go do a blind test now I bet you’ll find them easy to tell apart.
Do people think they taste the same ? I can normally tell them apart on smell alone.
