Homebrew PCBs

First a little background:
I've been using Autotrax EDA as well, and it seems ok.  I've also tried
eagle and vutrax.  All three don't really seem to meet my needs.  
There also seems to be a wealth of gnu/linux software out there gEDA,
XRoadMaker, PCB, etc. here's a list.

Ive also given altium protel DXP a shot.  The only package that i've not
tried is Orcad.  

My question is, what is standard for design. in industry and for
basement engineers.  Are some more cross compatible than others?  Are
there autorouters out there that actually work? Are there any really
complete schematic/footprint libriaries? or are most parts done in
house?

Thanks for any info.
