I personally feel that telephoto lens gives more emphasis & prominence to landscape photography.
Wide angle lens, on the other hand, helps to exaggerate the perspective to good effect but are not as easily mastered.
IMO, wide angle landscape photography works extremely well finding/using interesting foreground (such as rocks, pebbles, boats etc) to lead viewers' eyes to the main focal point and the background.
Whichever your preference, mix well with both types of lens to add some spice/change to your landscape portfolio.
