X windows and applications advice

[James Griffin]

Hi everyone, 

I wanted to run some xterms earlier and found I needed to install
XQuartz. Then I remembered (possibly incorrectly) that I could use X11
built using Macports.

Would you say using the X11 implementation is better in terms of using
and availability of X applications, many of which I will install using
Macports? I mean, the applications from Macports, are they able to be
used on XQuartz X server, I'm guessing they can be. 

I'm not experienced with X11 on Mac computers really so I apologise if
this is a silly question. 

Thanks, Jamie.
