I've had a look into this myself.
Assuming all your APs can support Client-Match (regardless of model specifics), I would personally recommend you disable all the older features like band-steering, and let Client-Match do it's thing globally.
Theoretically, it supercedes all the older features and it should be better. If you mix the features across AP types, you'll get variation in the result (and variation is not good). The older features were conceptually a bit more "pushy" than Client-Match which is much more friendly from an engineering point of view. So the result should be much more slick an predictable.
