I think I have a mutation in a taste bud or something, but Sucralose is really a prominent and nasty taste to me in anything it’s in.

The only artificial sweetener I get a nasty aftertaste from is saccharine. But I get a really absurdly foul aftertaste from saccharine, I can’t even compare it to anything because it’s easily the worst thing I have ever tasted in my life and I can’t think of anything even sort of similar. Glad basically nothing uses it any more, but it was more of an issue as a type I diabetic kid decades ago. Sucralose doesn’t give me an aftertaste at all though, neither does aspartame or acesulfame potassium.

My preferred sweetener though is stevia (I used to go to the local new age shop and buy just dried stevia leaves for my tea and such during the time it was legal to sell in any amount for any purpose as an herbal supplement so long as you didn’t mention it had a flavor which turned it into an unsafe food additive because fuck NutraSweet corp). It took such a ridiculous time to get approved because of NutraSweet, when stevia really should have fallen under GRAS status for the same reason things like tomatoes did - New World plant used in food forever by the natives, but wholly new to Europeans when they came to the Americas.
