My experience was that most of the time it was the cable, followed by dirt in the port.

Now PCB quality can also wildly differ and the bonding between substrate and pads can be a weak point if the manufacturer of the device went for the cheapest possible PCB. But for that you have through-hole USB-C connectors and cables that should break before the connector.

So if your USB-C connector breaks off the PCB that is on the manufacturer of the device.
