Pretty much the same but Vegas is slightly warmer.
According to USClimateData.com (using DFW International Airport since they didn't have a listing specifically for Frisco).
Average January high in Las Vegas: 58
Average January low in Las Vegas: 39

True. Vegas is a lot drier than Frisco. That site doesn't list any numbers about relative humidity but Vegas has about one quarter the average precipitation in the winter months that DFW has. I remember news outlets making a big deal last winter when there was snowfall accumulations on the Vegas strip for the first time in many years. Dallas has snowfall accumulation every winter (not much and it doesn't last for long but every winter they get some).
I think regardless of what the temperature is you would get to watch a Bison football game and then go back to quiet confines of Fremont Street. Frisco, Tx at the end of the day is still Frisco, Tx where as Las Vegas is well LAS VEGAS!
