I have the matte finish and my husband has the glossy (on our ereaders, no EE or PE yet). I would think you would like the matte better for burlwood and carbon. As you would expect, the matte finish is not reflective and the glossy is. It might be my imagination, but I think the glossy also shows dirt/fingerprints more than matte. Whichever you choose, you will have one classy looking machine! (Can I call the eDGe a machine? ;p)
Good luck!
