I love graphviz and have used it as part of my job for over 15 years.
That said, I have spent entirely too much time manually searching through the 100-odd dimensional Graphviz parameter space trying to get aesthetic results. So much time in fact that occasionally it's easier to fire up Omnigraph and draw the thing manually.
Graphviz would be ideal if it had some kind of meta-parameter settings that could reduce the tendency of its output to resemble an unreadable rats nest when the number of nodes exceeds about 20. I know that's part of the point of neato vs. dot, and that some parameters are effectively meta-parameters, but Graphviz still needs a better "porcelain" (in git-speak) with fewer dimensions.
