I believe there is a few other threads around here that discuss this very topic if you poke around.
Editor’s Choice really focuses on not just the food but the company itself. Blue is a bit shady in a lot of their practices, and while it looks excellent on paper (and many people do well on it) there are also a lot of people who don’t do well on it for no real reason, which can be concerning. Purina recently sued them for false advertising, but I haven’t actually seen the outcome, though Blue’s response didn’t win them any points with me. I’ve only used it as a transition once for a puppy that I got, so I don’t have much experience for it myself.
My other comment, is because Blue has become so commercialized, it’s sort of expensive for the quality, and there are other foods from companies that are more trustworthy, in my opinion
