Just use one film and one developer. As noted above, why? They make a variety because not one will work for everything. And these days, why standardize on just one and know just one when there's always a chance of it going away? One of the advantages of film is that with one camera you can use several different types of sensitized recorders.
And the cameras themselves come in a wonderful variety, for the same reason. And how would you know what "the one"" is if you don't give more than one a try?
