Both good brands, and don't overlook Monaco/HR either.
My advice is to look at as many makes and models as you can, in order to get ideas about what floor plans and amenity levels suit your wants and needs. Once you have settled on what works best for you, then start shopping the brands that offer what you need.
You also have to establish a budget target and decide whether new or used. Buying an RV is more like buying a house than a car, so used rigs should be considered. In my opinion, a newbie should start with a used rig if for no other reason than they are quite likely to be trading it within two years. Few RV buyers ever get it exactly right on their first try.
