I grabbed a 12 pack of the zero sugar version at the big box store the other day. I do like it. But, you can line up Starry, Sprite, the old Sierra Mist, 7 Up, and even the Walmart store brand, and I couldn't tell the difference. In fact, Walmart's lemon lime is very good. I'm sorry to say they never got the diet cola right.
Pepsi keeps trying. Remember Teem? How about Slice?
I'm an infrequent lemon lime soda purchaser, so I'll get whatever is on sale. Will Starry cause you to switch brands? I don't taste much of a reason.
