It depends on the environment where you are going to use it, there are systems that emit too much electrical noise, and interfere with the reading, and by the way when working with motor speed control systems, clamps with integrated low-pass filters are needed to correctly measure values that because of the amount of ammonics they are not displayed correctly in some multimeters and clamps ammeters, it is also good that you use a device that is True RMS. Something that is also important and some people do not pay much attention to the accuracy and accuracy of the equipment, for example the Fluke ammeter and multimeter clamps, are expensive because they have a high accuracy and precision, certified.
