The tough thing with Leviton 3-way switches is that you need to have a neutral wire at both boxes for them to work. You need both boxes to have a neutral wire as you will need to install the master 3-way switch in one box and then the Leviton Remote switch in the other location and they both require neutral wires. This also may lead to too may wires in the box for electrical code requirements as well.
From my experience, it's not very common to have a neutral in both switch locations. For this reason, it's much simpler to use a Lutron Caseta switch. With these switches, neither box needs to have a neutral and you buy one switch and then a Pico Remote for the other location. Or you may find you don't even need the Pico remote to act as a second switch as you may just eliminate the second switch all together if the lighting circuit is going to be controlled by motion and you'll never touch the switch anyways.
In my home I used Leviton Z-Wave switches in varies places, that weren't 3-way circuits, to build out my mesh z-wave network and then I used Lutron Caseta switches for all of the 3-way switches. If you do go this route, I would try and install Leviton Dimmers over the regular non-dimmer switch as the non-dimmer switches have a really annoying click sound anytime they turn off or on.
