It depends a lot on the gain setting, supply voltage and input voltage how high you will measure distortion and noise. With a low input impedance (input shorted) the noise should be in the same ballpark. The LMC has higher voltage noise, but its lower noise corner will compensate for it. OPA specs
8uVrms with 50k BW. The LMC has more distortion, with 40dB gain you will have an audible 1%, the OPA is 1-2 orders of magnitude better. You could shift the bias voltage down to +2V for 5Vsupply. this will reduce the crossover distortion between the input transistor pairs. Also the input impedance of the LMC depends a lot on the distance to the positive rail, so a higher supply voltage will help here too. Be a bit more specific about your application and we can give more detailed advise.
