I have a function that compares objects by each attribute to see if they are identical. But I was just wondering, would it be better to compare the object by their address instead of checking if they are exactly same objects?

You should decide whether your classes are meant to support equivalence or identity. Equivalence is a property typical of values, such as numbers. Identity is a property typical of entities, such as people.
Equivalence is usually determined by comparing the data members of a class; comparing addresses is a reasonable way to check for identity.
