A public, directly routable IP address which doesn’t cost a fortune for the ISPs. In fact, an incomprehensible number of public, directly routable IPs per user such that it’s an embarrassment of riches compared to ipv4 (the only important limitations are more down to the number of subnets per user, which is usually still way more than you need at 256 for /56 prefixes).
And it’s even better if all devices and networks support it, since you no longer have to rely on n layers of NAT, reducing latency and complexity.
