Landmark TL VS Landmark

Hi, Is there a difference in how they look? I know that TL is a better product but I was curious if Landmark TL also looks better than Landmark.
There is a significant difference in the price. I have been quoted $378 per square for Landmark and $509 per square for the Landmark TL (impact resistant), which includes everything. (all material and labor). I am planning to replace the roof of my ranch style home and was wondering if these prices are reasonable. BTW I am in Minnesota.
