Audio Spatialization: Meta VS Fmod VS Unity

Hello.

My intuition is that, to spatialize stuff in VR, one cannot use all 3 of them  together as they all attempt to solve the same thing.

What is the recommended approach?

Unity is likely the most limited one. So dropping that.

I have seen Fmod being used in VR without the Meta Spatial Audio. Does it make sense?

Because Meta Spatial audio seems to go really in depth (link). So my institution is to use Fmod as usual but with no spatialisation and then let Meta Spatial Audio take care of that.

Can it be done? Do they play well together?

Thank you.
