No.I prefer MosFet transistors to bipolar transistors because of less voltage drop.
The BS170 has an ON-resistance of 1.2Ω at a gate voltage of 10V, resulting in a voltage drop (loss) of 24mV at 20mA, whereas a bipolar transistor normally drops 0.7V.

No.
An ordinary little transistor like the 2N4401 has a collector saturation voltage of only 0.05V at 20mA, not 0.7V.
Maybe you were thinking of a huge 2N3055 power transistor at 9A.
