Is either moen or kohler compatible with delta or both of them are?

i have delta tub and shower faucets in both of my bathrooms.i would like to change them to a different named brand.|||as long as your changing the whole fixture, it doesn't matter|||I don't believe the parts are compatible. In choosing the faucet brand, be sure use a name brand and that parts for it are easily available in your area or favorite or local hardware store.
