Good to see you ordered your pads; hope you get them before the weekend 
Do you guys never order pads from Vx? If so are they good?
I use GM pads. Mainly because they are cheap, and I have to replace them every 4k or so. They are pretty good, much better than the junk most factors pedal. Generate an awful lot of dust though - go play in the ice with TC switched on, and mirrors pointing down at the rear wheels 
Granted they are cheap, but everyone has their own preferences for different reasons. I prefer (whatever the car) to buy good pads (along with good tyres) from respected brake manufacturers like Mintex, Ferodo etc.Each to their own. 
Never seen "Genuine GM Brakes" slapped over a Touring or Rally car tho

I agree, I
like need 'good' pads. Thats precisely why I
won't use the Mintex/Ferodo shite as sold by most factors and Hellfrauds (for Ferodo). Tried both those brands on the Omega, I really didn't get on with either (and both were binned within a couple of months), disappointing performance for both.
I find the TC ones have better stopping power, and last longer before fading to the point of not stopping. They are certainly not a trackday pad, but I need a pad that works when cold as well, so the likes of Red Stuff by EBC are out for me. And any pad that can fire the ABS at 3 digit speeds in the dry on excellent, soft tyres, and Irmscher suspension clearly has enough stopping ability. And can keep doing this about a dozen times in the time it takes to get back to speed before failing. Admittedly after that sort of abuse, they're utterly spent, and never fully recover enough for my preferences.
Not sure I would see the extra benefit of OE pads to make the cost worthwhile - many say there is better feel from them, but I don't seem to suffer from not knowing the braking threshold with TC pads.
What I will say about TC pads, once they are half worn, they can't take as many big stops in quick succession before fading badly.
