In general I love reading the code base of BSD-systems, NetBSD in particular is really beautiful and easy to follow.

I generally look at some BSD sources when I want to know how some unix tools are working, they are always much much more readable than the GNU equivalent.
I think unix v6 was mostly as clear. Linux suffered the real world penalty. But maybe BSD managed to keep it's source poetic.
