They serve different functions. WOL boots the operating system currently installed on the computer.
PXE runs entirely in the firmware, before any installed OS. PXE locates the NBP and executes it. In most enterprise deployments, the NBP is used to install a fresh copy of the OS onto the machine. Internet cafes often do this. Alternately, the NBP could boot an OS over the LAN; it's how diskless workstations start.
