A distinction though is that circut-switched loses connectivity when a circuit is broken. Packet-switched does not. You see some packet loss, there may be increased latency or reduced bandwidth, but the packets can still be routed without session loss so long as some valid routing exists. (For TCP --- I'd tell you the UDP joke but you might not get it ...).
To that extent, the packet-switched network is more resilient, and this was a conscious design consideration, as can be seen in Paul Baran's original packet-switched networking documents:
Simulation results are shown to indicate that highly efficient routing can be performed by local control without the necessity for any central—and therefore vulnerable—control point.
