Army, Navy, Scouts, Merchants, Marines... Wet Navy got shorted if I recall. COACC would have moved it to 6 I think. And a lot of other works (Dragon published a few, fans wrote a lot) filled out others. I wrote a corporate one.
I agree the skills were (for our groups) more but usually in breadth rather than depth. And they still didn't match the real life skills of our players (not enough points to go around). They wouldn't work with existing other chargen, but as this was all we ever used, and NPCs were given comparable levels as needed (most didn't need to be generated as their plot role was limited), so there wasn't a big issue.
Because I collected a lot of extended generation from all sorts of places (IRIS for one, I think I had one for bounty hunters, one for Law Enforcement, and so on), we never felt a shortage.
