Natural Balance and Pet Promise?

My cats have decided to stop eating Evo( they will only eat a few morsels and I am throwing away more than they are eating, so I knew it was time to try a new food. I bought Natural Balance at one store and Pet Promise at Whole foods. I have read here that Natural Balance is a good food, but what about Pet promise. My Male likes the Natural balance but my female wants teh Pet Promise . I know to make the change slowly but I was just wondering is this a good food? Thanks

here is the website for Pet Promise:

The Pet Promise doesn't look bad (I skimmed the dry formula and the chicken canned), though in the dry food, my preference would be for a product w/out soy flour, but really..if they like it, it looks quite decent.

I am also not a soy fan ... looks decent and like Pat it is give them the best theyll eat..

It seems like the girl likes simpliar formulas ... look at royal canin and nutro natural choice, if you dont like going all over for food ...
