If you are looking to buy luggage your grandchildren will inherit, these may not be the products you want, but you're going to spend two to ten times more money. B&R and TP are not the only options in this space at all. Just looking at REI (there's a store in Albuquerque) or online at eBags, you can shop brands like Eagle Creek, North Face, Gregory, Cotopaxi, Osprey, Patagonia, PacSafe, Matador, Thule, REI, and Timbuk2.
Shopping for luggage is complicated because there are so MANY ways to pack and transport your stuff depending on your style, preferences, tolerances, and needs. You seem prepared to go carryon-only so that will reduce your options tremendously. Try to have fun.
