What brands of Greek Yogurt are your favorite and why?

I had some Greek yogurt at on a vacation and I really loved it. I tried buying it at home and was sadly disappointed with the inconsistent quality of the yogurt. Sometimes it is smooth and creamy—just the way I remember. Other times it’s sour and gloppy. This is within the same brand and flavor of yogurt.

So I just wondered which Greek yogurts other people bought and had good luck with. So far, I’ve had the best luck with Mueller.
