I have literally never seen or heard of a Lightning plug or port "getting bent or broken". However I have heard of the hidden-male-inside-of-female port of on-device USB-C ports breaking at which point your device is trash.
"Apple’s lightning-cable product page contains over 2,300 negative reviews of the lightning cable, with an overall rating of 1 out of 5 stars"
Lightning connectors do have the advantage you can safely stick a toothpick in them to remove lint, I don't know if lint building up inside the socket is a problem specific to lightning though.
