The emitter follower or common collector circuit provides an ideal buffer amplifier and it is easy to design the circuit however a switch it is not.

Also, I think you overlooked the most important error in the original question, which is that the NPN darlington is used a a high side switch (which is never a good idea for an NPN device). In general, Darlingtons are more robust devices than MOSFETs, especially with inducive loads, so I think it's perfectly acceptable here. | |
