Range was referring to the range of colors your gradient goes through. Your start and end colors are very close to each other. So there is only a very limited range of colors between them. That is different in the smooth gradient you are comparing to. Its gradient covers a larger color range. I don't think you can substantially better results than what GIMP will create for you. But if you are not happy about the result, feel free to use different software or to patch GIMP to yield a better result.
