Stainless steel vs. glass?

I have been researching for a good coffeemaker, and I have boiled it down to the Technivorm KB-741. However, there are two versions of the same maker, one with a glass carafe, and one with a thermo stainless steel carafe.

BTW, the glass carafe version has a heated hotplate with adjustable temperature setting, whereas the stainless steel version does not.

Which do you think is better, and why?
