Zynk vs LocalSend

Which is better for sharing files, Zynk or LocalSend?

Zynk is the stronger choice when your files need to travel beyond the local network. Send to saved devices and contacts from home, work, or another country, with conversations, previews, share links, and a CLI in the same app. LocalSend suits offline handoffs on one local network, but it cannot send over the internet. Zynk covers both nearby and remote transfers.
