If you don't need polymorphism, then in general, you shouldn't use a class (though sometimes it might make sense simply because it's an easy way to get a reference type). Where it becomes more of a problem is when you need a few polymorphic functions and a lot of non-polymorphic functions (e.g. when a class has a few methods which get overridden and then a lot of properties which it makes no sense to override). In that case, you have to use a class, and then you have to mark a lot of functions as final. This is what folks like Manu and Don really don't like, particularly when they're in environments where the extra cost of the virtual function calls actually matters.
If a reference type is needed but not a polymorphic type, then a final class can be used.
