Personally ... ... I tend to prefer Supermarkets' own labels to the well~known manufacturers' brands.

Take, for example, Tesco's Butterscotch Instant Whip - which I have just prepared for tonight's dessert a few minutes before typing this post - delicious, it is, much creamier & full flavoured than say, the likes of its 'Angel Delight' equivalent. Cheaper too, at 0.29p, only a little over half the price!
