The master (CMC) is an easier fix ($100 + <1 hour labor) and often the culprit if you're having pressure issues but the clutch is still usable. The slave (CSC) usually just $hits the bed completely and leaves you stranded. So you might consider trying to replace the master first if cost is a factor.

However, beware that the failed master has likely introduced contaminants into the clutch fluid which will probably lead to quicker failure of the CSC. And the CSC will require dropping the transmission which is going to cost significantly more in labor (7 hours or so). As mentioned already, plan to replace the OEM CSC with either ZSpeed or Z1 aftermarket slave options. Start saving if you haven't already - it will be $1K easy. Depending on condition and mileage, you might also consider replacing the clutch while the transmission is out. Better than paying another 7 hours of labor to replace it later if its on its way out.
