I have 3 X1C’s and 1 P1S. The P1S was my second printer. The P1S prints every bit as good and fast as the X1C.
Having X1’s, the screen on the P1 is annoying and so is only going in 1 step increments when moving the bed up and down. Admittedly this is only a thing when I clean and lube the lead screws, but the X1 is much easier to do this with.
If I were to buy another it would be another X1, or whatever the new model is.
