Really? Pepsi is the same as its always been in the U.S. (OK, actually the recipe changed when they switched from sugar to HFCS, but that was a long time ago).
At least some places, like the UK, "regular" Pepsi is now reduced sugar and full of sweeteners [1]
I first worried I had covid or something when I ran across the new version because it suddenly started tasting differently. I've preferred Pepsi for decades because it tasted sweeter to me so now it's coke all the way for me.
