witch is a better solution
1 , 2 or 3
of course 2 may not work
another question is that T2 in circuit1 are act as base current source or not
 

Hi,

I´d say 3), because the power transistor here works like a voltage source = low impedance for surge currents.

1) is more a current source wich is high impedance for surge currents.

Circuit 1 is unstable without additional feedback loop compensation. Circuit 2 has errors, as already mentioned. Circuit 3 needs darlington transistors or additional current gain for high output current.

Consider OP output voltage range and required supply.
