> Virtually all artificially sweetened soft drinks in the Uk are sweetened with aspartame

A quick look at a few soft drinks I could think of, and their UK sweeteners:

  Fanta: Aspartame, Acesulfame 
  Coke Zero: Aspartame, Acesulfame-K, Enzymatically Produced Steviol Glycosides
  Pepsi: Acesulfame K, Sucralose
  Irn Bru: Aspartame, Acesulfame K
  Tizer: Acesulfame K, Sucralose
  Old Jamaica Ginger Beer: Sucralose
  Lipton Iced Tea: Steviol Glycosides from Stevia
  Ribena: acesulfame K, Sucralose

There seem to be no clear winners, with the most noticeable finding that multiple ones are usually used.

Acesulfame-K and friends is normally used in small amounts with aspartame; individually they both taste bloody awful, particularly Acesulfame K, but together they taste borderline acceptable.

Must say I wasn't aware there was so much sucralose in use.

A personal guilty pleasure is sugar-free red bull. Sorbitol, Sucralose, Ace-k unfortunately.

Huh, how much sorbitol do they put in it?! I thought that one was mostly only used in low-volume applications, because in large volumes, it's a laxative (AIUI this is why you rarely see sugar alcohols used as sweeteners in drinks.)
