I use syncweb all the time. I can't go back to just using noweb. Many of the subprojects in pfff have a literate document that is synchronized with the code using syncweb (e.g https://github.com/facebook/pfff/blob/master/h_visualization... ). When I have errors in my code, or when I debug my code, I do it on the generated code, not the tex document, so of course if there is a fix it's easier to fix the code directly and far later to synchronize.
