You have a gajillion options in the mat department, especially when you factor in the possibility of using combinations. I wouldn't even consider making a choice until you choose your TT and have it in your system, having assimilated its characteristics as supplied.
The Boston graphite and AQ sorbothane mats are very different not only to each other but compared to the stock platter/mat configurations designed into the TTs you're considering. Beyond that there are paper, cork acrylic, glass, ceramic, constrained-layer damped aluminum, steel, copper, Delrin, wool, foam, polymer options. And it only explodes from there when you consider stuff that is no longer in production but showing up on eBay and here. Certainly check out Herbie's Way Excellent series.
