Both are using for filtering, but the access-group one is used in a layer 3 port, who can filter for the entire lan segment who is connected to.
If you have a scenario where in a given lan you want to filter only to some hosts the access to a a give multicast stream, you can filter them directly at the switch layer 2 port with the igmp profile.
