I don't see significant difference for most private people. I guess the median has three phones, a tablet and a tv box, there's not much scope to improve the network for that use case. But IPv6 makes a difference for some other situations. If you operate a network with routers and such, it makes sense to have all connections to internal services use IPv6. Backup, file storage, databases, management interfaces, blah: Give everything its own IPv6 address, don't accept connections on IPv4, and allow IPv4 packets from 192.168/16 only to the outside world.
