Here are a few of my observations.

1.  MRTG is supported by MANY more people than PRTG.  
2.  MRTG has perl libraries.
3.  MRTG runs on almost any operating systems, not just Windows
4.  MRTG is easily reconfigurable for other resolutions of data
5.  MRTG has the ability to exectue external prgrams, not just grab snmp values
6.  MRTG has a clearly defined and well-supported upgrade path in RRDTool
7.  MRTG gets updated regularly
8.  MRTG is far more scalable (I am monitoring over 10,000 different targets, but PRTG documents it can only monitor between 50 - 100 elements)
9.  Where's the source?  Oh yeah, you don't get that...
10.  MRTG integrates into Big Brother, Nagios, and other NMS solutions quite easily
11.  Cisco uses MRTG for examples in some of its white papers

I'm getting tired of typing off the top of my head.  Pointy haired managers should manage, not 
make technical descisions.
