the fudged model you made from opamp2 won't misbehave when you drive a capacitive load, nor will it current limit the output or distort into a low impedance load. a model for a real component actually has SPICE netlists for inputs and outputs that allow the model to behave like a real device. however, the fudged model will not behave like a real-world component. If you know the OPA2134's GBW and Aol, you can approximate one.
