IBNS 2.0?

Has anyone here deployed 802.1x using Cisco's IBNS 2.0? Are there any benefits that outweigh the seemingly additional complexity that it introduces?

We will be doing a large-scale 802.1x deployment in the near future. I'm getting mixed messages on whether we should use the traditional 802.1x configuration or the newer IBNS 2.0 model. Cisco is obviously pushing the new configuration, but the re-seller we use is telling us to stick with the traditional method (I get the feeling that none of their SEs are familiar with IBNS 2.0 which is probably contributing).

Beyond future functionality, the only real benefits of using IBNS 2.0 that I can see are simultaneous authentication methods and smaller config files.
