"Classic" (old-style) classes are ones with no ancestor classes that are built-in types; "new-style" classes are one with ancestor classes that are built-ins (including the built-in type 'object', which exists for the sole purpose of making classes new-style). New-style classes have a clearer and better organized approach to attribute access, and allow you to use such powerful features as 'property' to full effect. Old-style classes exist only for backwards compatibility. The only good reason to decide to make a class old-style is when you're making an *exception* class, specifically: up to Python 2.4, exception classes must be old-style.
