While I am a big proponent of open source, a few are not good enough yet. The most important one being CAD. No CAD is good enough for serious mechanical engineering except commercial ones. The creative software (GIMP, inkscape) can replace Adobe but they are much harder yo use with worse integration between them. In the other direction, some OSS software are just way better than the commercial solution (I'd put OBS in those).
