I stopped eating chocolates when I changed my entire diet a couple of years ago, but I used to eat anything and everything, including Roses/Quality Street/Celebrations, etc.
Did I enjoy them? No, not really. One or two of them tasted okay in moderation, but what tended to happen was once the box was opened I'd eat quite a few in one sitting and they would all taste much of a muchness and sickly-sweet. Then I'd be left feeling quite guilty for being greedy, as well as generally sluggish and with a bit of an unpleasant aftertaste left in my mouth for a couple of hours.

Overall, it's safe to say they're not something I miss.
I still occasionally buy them though, as they're useful for when I want a cheap and cheerful token present for someone I don't really care about.
