Kit Kat
I prefer the old flavour. If I have a choice I will choose the original flavour than the rest of the new flavours.
 Time Out
When this first came out, I was buying it religiously if not every day then it will be every week. Did I turn fat? Well, I am lucky that was when I was pretty young and my metabolism is still kicking rather well.
 Cadbury Dairy Milk
I still prefer it's original dairy milk than those with nuts or whatnots.
I just had this last month after such a long time being distracted by Kit Kat and Time Out. The taste is still the same, however I find it is a bit too sweet for my taste bud nowadays.
This is very nutty and full of caramel. I love this when I was young. However, right now my preference is more towards dairy milk type. So I seldom have this anymore.
I still choose Kit Kat from all of the above. What about you? Which one from the above you like best?
