I am using 5V but when changed to bilinear they are actually 10V. 12V 28BYJ-48 motor were quite expensive, when I was looking for them. 12V motors would require more current and are going to be stronger. In theory, they should run cooler, but as I never had chance to test them. I cannot tell for sure.
