X all the way. Better reception than the Xs Max. Xs Max has a new antenna design compared to the X. The new design is horrible. In fringe areas the Xs Max will drop the signal, while the X maintains it. I had the Xs Max, and got rid of it because of that issue and kept the X. I now have the 11 Pro, and it has the same poor antenna design that the Xs has. I might get rid of it and go back to the X. Unacceptable that Apple is making phones that are worse with reception than models that are 2 to 4 years older.
