Welcome Jorgerod.

The question you ask does not have a definitive answer and I think you will find both camps on this forum on QS8 vs. direct radiators for channels 6&7 (though the camp can even change based on room configuration) .

My 2 cents is that I love the QS8's and the ambiance they produce. My previous system used direct radiators and I greatly prefer the Q's. And as I'm sure you know, the Q's can also be surprisingly directional, so to me they are the best all round surround speaker.
