I have a book which had a whole chapter on Dua Qunoot. It said that apparently, the different "madhab" follow different qunoot. And there were three listed in all, but almost the meanings for all were the same. I was always taught the "allahumma inni nastaeenuka..." one, but there are others. too.
Which one did the sahaba read, I wonder. I want to say just that, and not follow according to any "madhab"
