OSPF vs IS-IS

I'll go with that... And one other thing... Traditionally it has been easier for developers to add new features to IS-IS because of the structure and flexibility of TLVs, whereas OSPF required the design of entirely new LSA types to support similar capabilities... I guess this has become less of an issue over the last few years however...

Nonetheless, if I was building a greenfield network today, I would personally go with IS-IS, but that is largely because of my many years working with the protocol...
