We also have PADS users here, and between the problems getting them to 
produce documentation, and the BOM that PADS produces, and the dumb support 
staff in the UK, we are trying to get rid of it.

The other problem is the different standards that various designers like to 
use for schematic layout. I do not like the PIC parts that Orcad supply, and 
many of their other library parts are not much better.

Once you get beyond basic parts then things get that complex so quickly that 
it would be nigh on impossible to have a library that satisfied everyone.

Think in terms of using IEC standard logic gate symbols, versus standard US 
style logic gate symbols. Now have a library where each symbol has the leads 
come out on 1 grid line spacing, or 2 grid line spacing or ... whatever your 
local in-house standard is.

In short it comes down to a package you like most, and then make symbols for 
the library how you want ...
