It's different. Icomoon is brilliant for creating a preset group of icons which will be used in a predictable way. But sometimes, especially during prototyping, you don't know which icons you'll want. Just being able to include a pretty thorough library which renders consistently and gives you a decent level of control is a nice weight off your mind. It would be nice to have a subsetting tool, but imo that's what Icomoon's for. Btw, you can save fonts in Icomoon - just click on the save icon in the bottom right and it'll save a settings json file which can be reimported.
