I am already using Windows 10 IOT Enterprise as my main driver (the original version was actually Windows 10 Pro, but we can change the version easily using MAS Medicines. We could also change version from Enterprise LTSC to IOT Enterprise LTSC or vice versa, but only if the original ISO is LTSC version). Besides the activation method (regular LTSC requires KMS while IOT requires HWID), there is almost no difference in features between them except the IOT version by default doesn't create reserved storage. Most custom builds disable this feature anyway, but if I need to pick original stock ISO for personal collection, IOT LTSC ISO would be my number one choice.
