You're conflating two different things. Unless you have some very weird genetic condition, it does taste sweet to you. That is, it activates the same sweet receptors on your tongue and in other parts of your mouth that sugar activates - and more or less to the same extent (relative to concentration). However, sugar isn't simply a sweet taste. It also has some amount of flavor, and so do the artificial sweeteners, and it is these flavor differences that you (and many others) dislike. Flavor is something that happens in the air tract, and is far more complex than taste.
