SLAAC is the only way that works across all IPV6 devices. In that mode, the router advertises the prefix and the device assigns its own address (prefix + its mac address).
DHCPv6 exists but is poorly supported. It sucks for people who like assigning IPs individually from an authoritative place (through static dhcp entries on the router). But people like us are "doing it wrong", you see? We must accept that in this brave new worlds an IP means nothing.
Which doubly sucks in terms of assigning a DNS name to an IP/PC... and/or opening the assignment to less restricted access... feels just problematic to me.
Again, I don't know any of IPv6 enough to use it really right or wrong.
If your ISP offers it, you should just try it. If not, do you have a website on a VPS or something? Try making that work with v6. It's really not a scary monster, it's mostly the same thing again but with long addresses, and a few convention changes that come with long addresses.
Examples of convention changes: end devices can each get several addresses for privacy and for being on multiple networks concurrently. SLAAC is stateless because addresses in a /64 are so endless there's no need to keep a central registry of which ones are already used. NAT is rare because it's no longer necessary, even though there is no internet police to stop you from using it (please try to avoid it). P2P is so much easier - applications can be written under the assumption connectivity is end-to-end with firewall hole punching.
And there's always static configuration, useful for servers.
