It actually depends on what kind of recipe you use, savory or sweet?
Sweet you can use marscapone cheese
Savory you can use rigotta cheese, sometimes sour cream will work
As other have said greek yogurt
I personally do not care for cream cheese plain but sometimes you can mask the flavor with garlic, lemon, onion, crab, worscheshire combination and you wouldn't even know you are eating cream cheese. Usually for a dip like this mixture, sour cream and some mayo is added for an easier spread.
