Kanthal wire is popular for a reason, and has been for nearly a decade. It’s easy to work with, has good resistance to oxidation, it’s not springy so it holds shape, and it’s cheap and easy to find. Kanthal especially good for single coil builds, which are not extravagant but get the job done when you’re not in the mood for something fancy and time-consuming. Add to that the fact that it holds shape well when rewicking (which means that you can use a Kanthal coil a good long time) and you have a fan-favorite.
