GNU is usually fast, the code has good algorithms, the problem is that they don't care about SLOC and have the worst code style that have ever existed (at least in C).

Plan9 userland is good, specially in design, and for me it doesn't seems too hard to make it POSIX compatible, the problem is that hardly anyone has enough incentive to do this (as most of people don't care/understand about design/implementation quality)

To this day i would say that the BSD's have the best userland, the code usually has smart algorithms, the code style is pretty good, usually the code is not unnecessarily huge, and the code tends to be reliable (at least for OpenBSD, which creates new functions to avoid common mistakes)
