One thing I learned with Eagle (an old version -- I started with it on DOS, with a physical license dongle) is that you can define library stuff via scripting. This is very helpful when defining 120-pin PCB footprints.
I don't remember precisely, but I think you can export libraries from Eagle in some sort of text form. If that's true, then it would be SMOP to write a KiCAD library importer. The key question is whether the library semantics are compatible. EAGLE is rather nice in the way it handles schematic symbols vs. footprints and all that.
I used EAGLE long ago for one project, and more recently for another, but I haven't found it sufficiently useful to buy it a second time to get the non-free version. Not that I really need the autorouter, it isn't really all that useful. But still, it's pretty steep for a hobbyist. I discovered KiCAD, haven't used it yet, should give it a try.
One nice aspect of EAGLE is that a number of PCB fab shops will accept EAGLE *.BRD files directly, rather than asking for Gerber and drill files.
