Which is a better 6" PC pad? Flat or Contour?



Megs and The Edge are flat and some say provide a better contact surface using a PC, even though you have to learn to not splatter the product.



CMA contour (LC in general, I guess), etc., it has been said are really made for rotary use. (BTW, my white pad from Autopia was flat, but the cutting and finish pad are contour.???) The non-splatter design seems to be the stated contour pad advantage.



What is myth...fact...and who has the real world answer to which, if either, is best?
