If you're a home user, the advantage to Tailscale is that it's going to "just work", with a couple clicks, on any supported device (of which there are lots). There's no configuration to get started and, for a lot of users, no configuration ever after that. The onboarding experience is spooky; it's upsettingly good.
If you're a corporate user, the advantages are drastically greater: you get SSO integration (this is historically one of the annoying pain points of corporate access VPNs, to the point where a significant fraction of pre-Tailscale netsec teams just punted on this problem and hand-provisioned VPN creds for people, which is a nightmare) and trivially simple group-based access control.
