I think the main difference is that when I learned IPv4, pure-v4 was sufficient. Today, you can't run a pure-v6 network; you have to deal with both. The closest you can get is NAT64, which 1. doesn't always work, and 2. is still annoying to manage. (Which sucks, because doing just v6 would be nice)
