Someone correct me if I'm wrong but I can definitely live with the latter since I can't unlock at this point.
Removing write protection allows you to write to they /system partition. You can actually make most changes such as "modding" your phone without this, but in general they may not survive a reboot. PIE is actually a root method that jcase developed for the moto x. It essentially does the same thing as towelroot, but it requires you to be connected to a pc to use it. As someone else alluded to, you can install xposed after rooting with PIE, and it will survive a soft reboot. I haven't tried towelroot, but I would assume the same to be true there. The main problems with this are the lack of wp removal, and the fact that my moto x has a tendancy to crash sometimes immediately following a soft reboot, forcing me to tether and root again. I may try towelroot to see if it works the same. If it is successful, it may be preferable since it doesn't require a pc.
