Look for things like:

* IPv6 NDP support (RA, ND, NS, etc)
* IPv6 native transport to the control-plane + in-band management
* Support for IPv6 on bundled interfaces (with RA, ND, NS working)

These are the types of things you need to look for.  Some of these items depend on what your use case is.  Some places you may want to talk about RA-Guard, others may not matter as much.  Same for DHCPv6.  I don't need this in my core network, but at the edge it's possibly important depending on the device(s).
