What's the best software for wiring diagram?

Hello All,

We would like to find software that is easy to use and can generate wiring diagram with each signal connected to connectors. Currently, we're using Creo Schematics for interconnect diagram/cable schematics and Keycreator/Visio for wiring diagram. Does anyone use different software to generate wiring diagram beside Autocad, Keycreator or Visio?

Thank you in advance for your help.
