If you know in advance that you're not going to need a more powerful, more complicated/expensive/... tool, then it's okay and even recommended to use the "lesser" tool. If I need to screw in a few screws, am I better off buying a small screwdriver or a professional 18V screwdriver/drill combo with 24 add-ons? Who knows, it depends on my projects and my skills, but it's entirely possible that buying the $5 screwdriver is the appropriate thing to do.
