PMC GB1i or B&W CM7 - Which is better speaker design if needs to be close to the wall?

[madeinstein]

Hi out of these 2 which one will sound better if needs to be fairly close to the wall?? (10-20cm)

PMC GB1i or B&W CM7

And what is the optimal distance from the wall for these speakers?

PMC are less fussy with positioning imo.
