I don't want to sparkle a holy war here; I usually differentiate it in this way:

• For POD objects (i.e., data-only, without exposed behavior) declare the internals public and access them directly. Usage of struct keyword is convenient here and also serves as a hint of the object usage.
• For non-POD objects declare the internals private and define public getters/setters. Usage of class keyword is more natural in these cases.
