In my experience, and I used ZeroTier extensively before moving to Tailscale, it fails in a few points:

* Performance was never quite great, especially when NAT was involved. This may have improved, but I haven't used it in a while.

* NAT was hit-and-miss. It would usually work, but would not work frequently enough that I couldn't just count on it.

* Not really easy for some use-cases. Main one for me, having a router both for acessing my LAN from outside, and as a gateway to my home Internet (akin to a VPN service like e.g. Mullvad or PIA). It's possible, and I did use it that way but it required some iptables-fu and it would fail some times - when it did, I would lose all my ability to connect back. This is especially bad if I'm traveling, since I don't have physical access to the router to fix the config. This never happened with Tailscale.
