Not really, I think it comes down to personal preferences. I read that Meguiar’s pads had a problem with the velcro coming off, but that has supposed to have been fixed.
The LCM pads had too small of a diameter velcro that allowed the backing plate to cut into the pad, but they redesigned them (although not all inventories may be purged yet). Some of the LCM pads have a concave center, called a "Variable Contour, Polish Pocket� that some may prefer. You may want to search around the forums and see what some other users like, but I’ve read good things about both companies pads, although the only experience I have is with the Meguiar’s (which has been positive).
