Zynk vs Magic Wormhole

Which is better for sharing files, Zynk or Magic Wormhole?

Zynk makes repeat transfers straightforward: choose a saved device or contact and send from the app or CLI. Browser share links let recipients receive without a compatible client. Magic Wormhole provides encrypted handoffs through single-use codes and compatible clients. Choose Zynk when you want remembered recipients, conversations, previews, and a native app alongside terminal automation, without exchanging a fresh code for each transfer.
