I used to use Netcat and now more and more Cryptcat. My understanding was Netcat6 was written to work with IP6 which is fine for places like Japan, but not really encountered here yet. To me Netcat is still a very useful utility depending on the level of security you encounter. If you are lucky enough to find a box that is vulnerable to that old dcom exploit and you want to use the exploit that was ported for windows, you have to use Netcat. In my experience, if you can achieve root, then netcat is still a viable option. I would say I am not ready to dispose of it yet, but Cryptcat is every bit as useful as netcat, with the added bonus of encryption thrown in.
