It depends on what you want out of it. MRTG or Cacti (or netdisco, which I'll be implementing here when I have a few moments to breathe) require SNMP access to your switches and/or routers - if your equipment doesn't support SNMP, or if you don't get that access from your network people this won't work for you. These will give you good readings on your network by port and in aggregate.
NTOP will not give you the kind of fine-grained view that the others will, but if you only have access to a span/mirror port on your switch(es), then it will give you a very good aggregate view of your traffic, but only your top three talkers at any given moment, or or any given period of time. These tools are complementary - use both if you can, even if you have to dedicate a couple of old desktops to do so.
