I'd try Zenoss. I wrote a big paper comparing Nagios, OpenNMS and Zenoss ( http://www.skills-1st.co.uk/papers/jane/open_source_mgmt_options.html )
- it's nearly 2 years back now but many of the basics are the same.
At that time, I plumped for Zenoss but, to be fair, my main negative on OpenNMS was that it is written in Java - it did pretty-well everything I needed.
Java programs may have a slow-startup, but why is it a negative for a long-running server program? The required JVM is included in the yum repository so installing isn't an issue and it seems like a big plus if you use the remote monitor feature (works via RMI). Also OpenNMS has had a lot of development in the last couple of years. Maps are in the core code, much more configuration can be done through the web interface, lots of ajax-y stuff to make the interface easier to use, many more devices included for auto-recognition, etc.
