So, I'm Greek and like Greek yoghurt, but unless I am totally missing something, it is nutritionally pretty similar to plain (unsweetened) American-style yogurt. It's just drained; the name is Greek is literally "strained yoghurt", and you can get an effect that seems pretty darn similar to my taste buds by buying a typical American plain yoghurt (note: vanilla-flavored sweetened yoghurt is not "plain"), and draining it overnight with a cheesecloth. But then I mostly use my home-strained yoghurt to make tzatziki, so I might be missing some of the nuances if you eat it plain.
If I recall when I was doing my research, one of the selling points of Chobani is that it's got 2x the protein of traditional American-style yogurt (i.e. Danon, YoPlait, etc.) Those all have 6-8g of protein / container, and Chobani has 14-20g, which is awesome when you're on a high-protein diet.
