I quite like the clarity of using link-local addresses within IPv6 addressing, along with scoped multicast. Replacing the functional of ARP from within the protocol (as opposed to ARP itself, which operates as a sibling to IPv4 with its own Ethertype) is quite elegant. DHCPv6 operating without the hack of using destination 255.255.255.255 and source 0.0.0.0 addresses, and thus without requiring special OS level privileges, also feels like a nice simplification.
