That depends on the technology you are designing. What is exactly your need? Why you ask for the mobility? Do you build a model for a specific application/case study?
See e.g. the MOSIS WAFER ACCEPTANCE TESTS for an appropriate process (scroll down for Spice data -- adapted, of course, but quite usable in case of mobilities).
This is true; still electron mobility is bigger than hole mobility at comparable doping & temperature.
Just think what "holes" really are: electrons with a lot of stopovers ;-)
