I use class method for generic actions that are not to be performed per instance of data. But if I have multiple instances of data then instance methods make more sense.
Some classes offer both instance and class methods doing the same process. So in the end its up to you there is no golden rule. For example you may have a class method that return the instance of the class which you can then use to trigger additional instance methods.
