Zerotier is not the same as tailscale although both can be used to do the same, but under the hood both are fundamentally different, ZT is layer2 like switch, so it’s like an Ethernet meanwhile TS is built on top of wireguard and is layer3. ZT allows broadcast/multicast and has own protocol, TS don’t. I use both among others, and ZT since around 2019, I found it reliable in some cases in IoT world while TS had better throughput in usual applications.

Yeah, they're not direct replacements. I think both models have have their pros and cons. In fact I tried both around when covid shutdowns started (server being in the office, me at home), and liked zerotier better; it was faster, and a more generous free tier. But now tailscale has won out for a couple of reasons; the main one, it's simply less flaky for us on macOS, especially for devs working overseas. No idea why and maybe there's simple fixes (that don't involve repeated connections/disconnections, hopefully). The other, tailscale has a few extra things that are nicer and easy to use like identity-based ACLs, funnel/serve, magicDNS, ssh management, etc.

Zerotier works fine for me, but with a huge exception which I just can't figure out. On my Linux laptop which also runs OpenVPN and with some specific routing set up, Zerotier will, after a minute or so, completely take over the routing and default everything through Zerotier, and nothing I do with the routing tables will change this. I have to stop ZT at this point and then it reverts to normal. Every other computer in my ZT network behaves fine.

This is so problematic that I'm considering looking into Tailscale, I understand they work very differently but it looks like my use case could be covered by both.

I had to do MTU tuning on macos on the ZeroTier interface (find your feth name via ifconfig)

# Replace feth1234/feth2345 with your active interface

sudo ifconfig feth1234 mtu 1400

sudo ifconfig feth2345 mtu 1400

..and for working with Windows peers, manually "Orbit" the Windows Peer as well as adding a direct routing hint for the internal ZeroTier IP. ZT definitely takes some effort for tuning.
