Went through the same issue with DD2. For us:

CC was the most convenient with hours and the fact it is open during the school holidays. Some of the children there will be going to the same school as DD2 (but not as many as the kinder)
Kinder has an integration program with the local primary where DD1 currently goes (so therefore so will DD2). Over half the children end up going to the local primary school, so she can make friendships that will continue on (so important here in a smaller community, much harder for newer kids to fit in).

We have chosen a combo of both due to my work hours, childcare will be on off kinder days with one combo day. Kinder has after kinder care for 2 of the 3 sessions (hence the 1 combo day)

For me the integration and the social side of kinder was more important than the difference in learning between a stand alone kinder and a kinder/childcare program.
