I had Pagid all round on my last Vectra, stopping power was very noticeable as was the little amount of dust on the alloys, I never noticed any undue fast wear and the discs did stay clean and shiny instead of rusting.
It's all down to personal choice again, hard pads for longer wear or softer pads for stopping power, Pagids have a good balance of the two in my opinion, my ZT currently has Delphi pads which are okay but the rear discs are quite bad now so I will be fitting Pagids across the back in the next couple of weeks and across the front before winter.
