That's debatable. I'm not hating on GNU or anything but that's kind of a relative claim and depends on the case-by-case basis. Claiming that all the GNU software is better than anything else is not exactly an unbiased claim, although it's still impressive hnw Stallman and his team were able to make a complete operating system in such a short time. Not as cool as TempleOS but still. Really makes you think that the BSD folks' claim of GNU+Linux being inconsistent is false because it's mainly due to the software that wasn't developed by the GNU Project.
