Have to experiment. Even the same speakers are different in every room.
It's true there is a trade off between strong centre image and wide soundstage.
Question about speaker angle
I've always been under the impression that your front main speakers should be angled so that the "face" of the speaker is basically perpendicular with the listener's face when viewing the speakers from the sweet spot. I do however see others placing the speakers parallel or inline with the surface of the wall behind the speakers. I'm wondering, how much loss to the sonic sound stage this creates.
