Its an unfair comparison of NPN and PNP as in most demostration. Check this, both transistors perform identical. But a current limiting resistor is a good idea to not burn the LED when Beta does change, e.g. with temperatur or aging or production differences. http://everycircuit.com/circuit/5354684974628864
