Which is better on a drip coffeemaker – a glass or thermal carafe?

Filter coffee machines use either a glass or thermal carafe. The glass carafe uses a hot plate to keep the brewed coffee warm while the thermal carafe will retain the coffee brewed temperature through insulated walls. There are benefits and drawbacks that outweigh each option. It is said that the hot plate used on the glass carafe will cook the coffee over time, tainting the freshly brewed taste. The thermal carafe retains temperature better.
