Which tastes better, 7-Up, Sprite, or Sierra Mist?

Sprite gets my vote as I get it free at work.

7-up would be a good energy drink,Sprite would be a snack time drink, and Sierra Mist would be a good late-night drink

So basically it depends on when you want it.

I think 7-up has the best taste out of the 3, but I find Sprite more refreshing and Sierra Mist just seems like a cheap alternative that will do when I can't get either one of the others 

My favorite is 7-UP ..............................

I prefer 7-Up to Sprite or Sierra Mist.

I've tried them all, but I never tasted them side-by-side, and it's been a long while since I've had any of them. I think I'd like Sprite the best.

I can't tell the difference, but I like 7-Up.
