iOS cluster control is a technique for centrally managing and batch-operating multiple iPhones from one computer, with no jailbreak and no signing.

This one answers: How Should iOS Cluster Control Connect? USB vs WiFi.

The difference is cable vs wireless,both can run scripts and view multiple screens.

Choose USB when

  • Many devices in one rack or room
  • Long sessions viewing screens and debugging
  • You want the most stable wired link

Choose WiFi when

  • You do not want cables everywhere
  • Phone and PC are on the same WiFi
  • Desks move occasionally

See the comparison in Connection guide. When unsure: connect one device over USB first, then decide if WiFi saves effort.
