Awesome tasting plain greek yogurt

I love the taste of plain yogurts (and kefir), so I have tried many different brands to see what I like the best. I have tried at least 6 different brands of "plain greek yogurt" and so far I like Riviera the best.
First, I like my yogurt a little runny--almost not a greek yogurt consistency. This Riviera plain greek yogurt (0%) is not as thick as other greek yogurts. Second, it is not as tart as some other plain greek yogurts are.
I bought this from my local grocery store when it was on sale for about $4. I think regular price was about $5.5, which is the same as other brands greek yogurt.
So overall, I prefer this consistency and taste vs other greek yogurts and the price makes no difference.
