It is nice to have the "best" or as good as you can afford or feel comfortable in spending the money for. It's difficult to know which brands/models to stay away from but most brands are of reasonably good materials and workmanship to be able to sell. I suspect that some manufacturers hire unskilled labor, use spot checks of assembly quality, and do not functionally test appliances and devices for proper operation before delivery to dealers. Dealer service departments are often backlogged negotiating with manufacturers for repair costs and correcting new rig defects.
