Certainly knowledge plus gear is the best situation. But knowledge is probably most important since many survival situation revolve around decisions made as to actions to take.

Coming to a flooding stream,do you cross or not? Do we climb this cliff, even though we don't have a rope or climbing gear? I see lightning, should we seek shelter or forge ahead?

The gear has no value unless the owner knows how and when to use it properly - indeed the goodies can get you deeper into trouble if not employed appropriately.
