From experience, can anyone tell me the best method of integration between NNMi and OM, web services or OM agent?
From my experience, the web services seems to have some kind of limitations. We notice sometimes that incidents are not being forwarded so we disable and re-enable the integration. On a couple of occasions we had to restart NNMi.

I use the OM agent (opcmsg) to forward the messages to OM. The opcmsg is invoked by the automatic actions in the incidents. This gives me a lot of control because I can ran any script and execute a lot of parsing or information gathering to enrich the information passed to OM.

templates are used by the agent running on NNM to match conditions,
like a snmp link-down trap. In OM 9 I think they call templates - policys or
something like that.

I have not done the integration via the agent before. I've always did it via the web services.
FYI, my experience lies in HP Network Management Center and I have a colleague who works on OM. To that effect, I only deal with the web form on NNMi's side.
It seems to me that most people opt for the agent integration.

Its not difficult (with caveats of course) since theres a utility in NNMI called nnmopcexport.ovpl which will build you a template that you can load into OMU composer.
The main caveat is that support for SNMPv1 mibs is broken. Using v2 mibs theres an offset value for things like Hostname, hostIP address that are shifted based on the number of varbinds a snmp trap might have... its currently broken and you have to manually calculate that value offset.

We've switched to the integration via the agent but we're facing the issue where an open incident in NNMi gets closed, this does not reflect in OM (the event is not acknowledged).
With the web integration, when incidents are closed in NNMi, this gets reflected in OM.
Help would be much appreciated.
