Diet puts it in the why bother category...
Personally, I grew up on diet soda, because it's what my parents bought. When I became an adult I tried regular soda, and I didn't like it. Too syrupy and sweet from the HFCS. I tried Dublin Dr. Pepper and liked that, but it too was very sweet and too much hassle to get to make it a regular thing. What was interesting is that in Germany, they sold "Coca Cola Light" instead of Diet Coke, and it had Cyclamate (banned in the US). It's pretty good.
