Always vanilla, because you can do so many things with it. Eat it plain, eat it with toppings, eat it alongside a heated dessert, make affogato or iced coffee, etc. I only buy “ice cream”, though. In my opinion, anything that can’t meet the minimum milk fat standards (and therefore can’t use the words “ice cream” on its packaging) is usually pretty bad compared to stuff that can. It’s either noticeably less creamy or it has a weird artificial creaminess (a good example of this is Peter’s). I’ll buy Bulla or Golden North if they’re on sale, otherwise I go for Foodland or Drake’s home-brand.
