When you select the use constant coefficients check box, you specify the polynomial expression in the constant coefficients parameter. You can also use looptune to tune control systems modeled in simulink. If you do not specify an operating point when linearizing a simulink model, the software uses the operating point specified in the model by default. One difference is that looptune needs to know the boundary between the plant and controller, which is specified in terms of controls and measurements signals.
