Right, the most obvious difference is that vvvv is visual. Then comes the "live-programming" aspect which means that in vvvv you don't "edit-compile-fixcompiletimeerror-compile-run" but you always only run and modify the running program. Compilation happens in the background. If there is a compile-time error, vvvv points that out for you, but keeps running. runtime-errors also don't necessarily completely stop the program. So while in the end you can certainly achieve the same things with vvvv and processing, the way you do things is very different.
