6to4 and 6rd are not the same and are not compatible. 6to4 has a given prefix while 6rd uses a prefix from the ISP to circumvent the case that a IPv6 packet which should be received by a 6to4 host never traverse a 6to4- gateway and so will never enter the IPv4 net. In this case the packet will never reach the 6to4 host. There is no way to guarantee that a 6to4 gateway will ever traversed so this indeed a big weakness of 6to4.
