Same here. It's not even the difference in sweetness, it's just the disgusting aftertaste that lingers forever. I've never gotten how people can drink Coke Zero voluntarily. Too bad they only sell caffeine-free Coke Zero and not the caffeine-free regular where I live, so I gave it another chance not long ago, but noped out after the first sip. It's undrinkable.

Though I prefer actual sugar, some low-sugar drinks use stevia, which doesn't have the same drinking-chemical-runoff taste of aspartame.
