Essentially Tailscale is WireGuard, batteries-included. Instead of configuring WireGuard on every device you want to connect, you can just install the Tailscale app. There are trade-offs, of course, but generally Tailscale saves time & can minimize headaches.
If you are happy with your WG setup and you don't need to fiddle with it, you won't gain anything by switching to Tailscale. On the other hand, if in the future you get annoyed when you need to add WG to a new device and try to remember all of the config options, or your networking changes and you need to update settings, or maybe you're rotating your keys, and you think to yourself, "man, this is an inconvenience!" - just remember that Tailscale is waiting for you...
