I like Splenda way better than any other sugar substitute. It measures the same (1 c. splenda = 1 c. sugar) and the taste is very similar to sugar. It's a little spendy, so I mostly only use it in recipes that need to be cooked and still use the pink or blue stuff in tea, coffee, etc.
They're starting to use it in diet drinks and such now too! Diet Rite Cola is made with it and for my $$ tastes MUCH better than either if the Big Guys' diet cola.
