No, tunnels do give you one to one global IPv6 address mapping for every device. From a testing perspective, a tunnelbroker  works just as if you had a second IPv6-only ISP. If you're fortunate enough to have a dual-stack ISP already, you can forgo tunneling altogether and just use an IPv6-capable border firewall.

Nobody is recommending the Apple router as a border firewall. It's terrible for that. But it's a ready-to-go tunnelbroker gateway. If your ISP can't deliver IPv6, tunneling is the clear path to building a lab. If you have a dual-stack ISP already, the clear path is to use an IPv6-capable border firewall. 

So you are in a maze of non-twisty paths, all alike :)
