I prefer the Star Mix over the kiddie mix my self, and the tangtastic over all others, even if it does make my mouth go numb :S, its a bit weird you don't get em in the US through :/.
Cadbury's chocolate is indeed not the best out there, but its a great every day chocolate, and still yummy. If I want to go a bit more high class I like to get Green and Blacks, but thats more of an adult thing :X
The maya gold is slightly orangy, and slightly spicy as well, great stuff :X
As for other kiddie sweets, Sherbert fountians are always good..
And I just love Swizzle double lollies
