Ghostscript can convert some PS files which Apple's pstopdf cannot.  
With Ghostscript you can choose to create PDF-1.2, PDF-1.3, or  
PDF-1.4 output, while pstopdf produces the system's PDF version.

I think the preferences show this only ... Apple's distiller is /usr/ 
bin/pstopdf. It has a man page.

Not when you use pdfTeX, because pdfTeX cannot handle EPS, so the EPS  
content is converted either during conversion (epstopdf package) or

This depends on your preferences, you decide which programme does the  
job. But this is a guess, I do not use TeXniscope to view PDF  
(TeXShop is my choice). Besides, when you pass a DVI file to  
TeXniscope it's dvipdfmx that converts DVI to PDF. Its config file  
sets Ghostscript to be the distiller, but of course you can change  
this and use for example Frank Siegert's pstill ...

I think: nothing else. You have PDF output and TeXniscope just  
displays this. I never saw something different.

There is the command 'man pstopdf' to inform you exactly about this.  
Usually it's OK to invoke 'pstopdf <PS file>'.
