What cat food should I feed now after the recall?

My cat was eating California Naturals and I just saw that it was purchased by the IAM's company which is notorious for putting crap in the food. Last year my 8 year old cat stopped eating after his cat brother died. I tried all types of food and he refused to eat. He hates wellness, solid gold and felidae. He will tolerate Chicken soup for the cat lover's soul but I've heard some things that aren't great about that food either. Should I switch back to that? He doesn't like wet food and I've tried all kinds and restricting dry food. He refuses to eat for days if I don't offer dry. He likes dry food which is triangular in shape like California naturals. He also likes holistic selects fish formula but again, I know fish is not good as a staple. What should I do? My choices now are Chicken Soup for the Soul or Holistic Selects fish based.
