Also, unlike Eagle and Orcad and circuit studio, Fritzing is free as in beer and speech. Same with KiCAD, but the learning curve on Fritzing is just so much easier.

Kicad is easy enough. I just followed the tutorial.
Since the changes that CERN made, KiCad is a completely new tool. It is now my tool of choice, and unless gEDA gets a similarly drastic revamp, I'm probably never going back.
I've not got any skin in the game as such, but occasionally think about contributing to it - usually after getting irritated by random UI things, but so far it's never quite been enough to dive in and fix anything.
Regarding libraries, in the hobby community Eagle has lost a lot of momentum in the past couple of years. KiCAD is now what you see a lot of makers releasing libraries and stuff for.
