Regular soft drinks, or Zero Sugar soft drinks?

I've tried Zero Sugar Pepsi, Dr. Pepper, and Snapple Ice Tea. I like the taste and not that diet Pepsi yucky taste I hated. Now, I'm wondering what the downside of Zero Sugar drinks is. Have you trid them or are you stuck on the full sugar varieties?
