Here, we have Coke Light, and Coke No Sugar (formerly known as Zero). Coke Light probably tastes similar to Diet Coke, while Coke No Sugar has sucralose instead of aspartame to make it taste closer to regular sugar/HFCS Coke.

Edit: in which market do you say sucralose being used in “no sugar” coke? I can’t find any reference other than to “diet coke with splenda” (a brand of sucralose, which is used in combination with aspartame in that “diet” coke).
That would be Singapore. Here's a hotlink to an ingredient label images from one of our online supermarkets:

I used to remember aspartame being present in Coke Zero, so Coke No Sugar (which seems to be marketed interchangeably as Coke Zero Sugar in this case) could actually be a new formula.
The zero brand seems to have been retired, and both "no sugar" and "light" use sucralose + acesulfame-K as sweetener (that's also the case for the US "diet coke with splenda” I mentioned, I mistakenly said it contains aspartame).

It seems, however, that in other countries both "no sugar" and "diet" contain aspartame + acesulfame-K (and cyclamate in some cases, but it's forbidden in some countries).
Personally I was a fan & regular drinker of Coke Zero. But I tried Coke No Sugar & didn't like it as much, and I switched all my spending to Pepsi Max once Coke Zero was discontinued. Interestingly, in Australia, Pepsi Max is owned by Asahi and is the #1 diet cola, even above the Coca-Cola brands.
