Hi all I'd appreciate your help. New to this.

I've got an upcoming J class trip with MH so I joined Enrich to earn the points. I'm a QF FF and that is who I have the most points with. Now this is where I get confused. As both airlines are One World members which membership am I best to link to my booking? I've done some quick research but can't seem to find the answer I'm looking for. Hoping someone can point me in the right direction.
