Wellness not as good as it used to be?

My local pet store owner told me that Wellness is no longer the high quality food that it used to be. He said the company was sold a few years ago. Apparently they began selling Wellness in the large chains after the sale (PetCo, PetSmart, etc.) and the quality went down. He recommended a brand called Fromm, which I'm not familiar with.

Does anyone know if this is true about the lower quality of Wellness? I have so much trouble finding something my cat likes. I finally found that she loves the Wellness Signature with the skipjack tuna. I still can't find a dry food she likes other than Science Diet Light. I know that's definitely not the healthies food but she simply won't eat the others. She needs some dry so I can leave it out all the time, otherwise she doesn't eat enough.
