The biggest tangible benefit is you don't need to worry about NAT port mapping any more. Every device can have a public address, and you can have multiple servers exposing services on the same port without a conflict.

(The flip side is having a network-level firewall is more important than ever.)

You also don't have to worry about running a DHCP server anymore, at least on small networks. The simplicity of SLAAC is a breath of fresh air, and removes DHCP as a single point of failure for a network.

So the benefit is that you dont need to worry about NAT for a couple of port forwarded services you may use (which might well even use UPnP for auto setup), but the tradeoff is you now need to think about full individual firewall protection for every device on your network?

I'll take full security by default and forward a couple of ports thankyou!

Few people care about exposing a server in the first place, even fewer care about multiple servers on a single port.
