I was wondering if any one can help me decide on which brand is better. Wellness or holistic select?

Lucky was first fed on Nutro Natural Choice when he was a puppy from the breeder, and now he is on Wellness Super Five Mix dry food. He is very healthy, and doing really good on it. I know that Eagle Pack's Holistic Select and canidae is also very good brands. I've looked at the ingredients list for the brands, and all three seems to be very good. I just can't decide which one is better. Which one do you prefer?

And out of that three brands, which one is the best for picky dog? Lucky is extremely picky!

Thanks! : )
