I'm not sure how much better their quality control is (they are another SV startup), but I have been eating Mealsquares (http://www.mealsquares.com/) for about half of my caloric load for over a year now and couldn't be happier. I also like the fact that they are solid food rather than liquid, just as a preference. I'm sensitive to gluten, corn, and soy, so Mealsquares are a huge boon when I am in a rush or need to opt out of eating somewhere (e.g. traveling).
