Calling methods in super class constructor of subclass constructor?

Passing configuration to the __init__ method which calls register implicitely:

class Base:

    def __init__(self, *verbs=("get", "post")):
        self._register(verbs)

    def _register(self, *verbs):
        pass


class Sub(Base):

    def __init__(self):
        super().__init__("get", "post", "put")

Or calling register explicitely in the subclass' __init__ method:

class Base:

    def __init__(self):
        self._register("get", "post")

    def _register(self, *verbs):
        pass


class Sub(Base):

    def __init__(self):
        _register("get", "post", "put")

What is better or more pythonic? Or is it only a matter of taste?
