With virtual short method you set + and - terminals to the same voltage but 0 current between them.
This is only true for negative feedback cases but that's the most common case.
It is easier in most cases than infinite gain model IMO. Once you have voltage and current of that location figured out, everything else in the circuit is solvable by freshman level analysis.
With the infinite gain concept you can use a limit to calculate the behavior of any circuit.
