I never said each method isn't applied equally to all players. But if different methods are used, players are not always going to fall at the same ranking in each method. And if each method produces different numbers for each player or doesn't produce results ranking players in the exact same order, then clearly it's not something that is 100% reliable and must be taken with a grain of salt.
There are concrete, measurable stats (BA, OBP, homers, runs, etc.) that are finite - you can't calculate them differently and come up with a different result. Metrics like WAR leave room for discrepancy. By and large, they give you a good approximation of who the best players are, but there are flaws since it is not a concrete stat.
