"Old coke", as well as what is now known as "mexican coke" in the USA, used/use sugar.
New coke was the flag day for switching to a cheaper sweetener in the US market. When they switched "back" to coke "classic", they kept the new sweetener.

First, people have done triangle tests on sugar- vs. HFCS- formulations of Coke (Serious Eats has a good one) and, while there is definitely a perceptible difference, the preferences aren't what you'd expect. People who go into these tests saying they prefer cane sugar Coke tend actually to reveal an HFCS preference in the test.
Second, formulations in different parts of the world vary in ways other than which sweetener they use. It's possible that regardless of the sugar involved, there might just be more of it in the formulation (or in the way it's delivered, since concentration systems also vary) in your least-preferred Coke instances.
Non-lite/diet/zero coke is always sickly syrupy oversweet regardless of whether it's sugar or corn syrup. It's sort of what people are going for. I can't believe I used to drink liters of it a day growing up; I limit myself to a dozen servings a year or so (of the full sweet stuff) these days.
