I usually get both and thought the new format of the Golf+ was initially quite good. But now, it may tail off a bit from the usual golf to incorporate more of the VW/Audi family as a whole. If this happens to great degree, then I think they may do themselves more harm than good. After all, the magazine is called "The Golf", and not "The Golf and every other car in the family". So who other than Golf owners and enthusiasts will even give it a second look, let alone buy one and check itout.
Never really rated PVW, as JV says - it is where the big money is spent, also it concentrates to much on the stateside scene.
