3310, am010, 3898, 3366 sensors do a really good job tracking every surface. Not worth sacrificing comfort and high friction of a cloth pad for (supposedly) better tracking in your case.
WARNING: personal opinion below! (Click to show)
Got to test a logitech g440, and I'd never sacrifice cloth pads for hard ones. I didn't notice a difference in the tracking and the slick surface isn't my cup of tea. Now use a "Gembird Gaming Pad", used to use a QCK+.
which brand offers the best tracking?
Any one-colour pad. Could be any colour. Some sensors (e.g 3090) don't like the change of colour of a surface because they "see" in black and white, and adjusts white balance according to your pads' colour. Rapid change in white balance could spaz out the sensor.
Brand doesn't make a difference, non-branded ones work the same. I'd recommend getting something that is available in your area, is the right size, satisfies your right amount of friction needs and comfort level.
If you are used to the qck and like it a lot why not buy another one? Unless you have some problems (mine has dust problems) or you want to change something we can recommend you something if you give us what you want in a pad.
