I would like to start a thread comparing these popular series. I have used Headway quite a lot, especially in the upper ranges, and like it. However I have also heard good things about Cutting Edge (which I have never used). Any comments by people here who have experience of either or both would be greatly appreciated.
One opinion that I have found on-line:
Dueling Coursebooks: The Headway/Cutting Edge Debate | Guide to TEFL
One problem with Headway is that it has been used so widely that it has become something of a cliché.
I have noticed a certain boredom with it on the part of teachers - I would be interested to know if that is shared by students. Personally I used it mainly when it was still quite new, so this didn't really apply.
