Death Magnet #1: The best product wins
.... Unfortunately, the best products don't necessarily win if another product is, at a minimum, sufficient plus quick to market, well promoted, and revised (churned) accordingly.
Why? Because of the Law of Increasing Returns. The more a product sells, the easier it is to sell. Other products may be better, but people get locked into a product and sales snowball even though it may be inferior.
