I went through lightning cables fast. Unsure why, maybe I sweat a lot, or keep my phone in humid places.

But every so many months I had to replace the cable because the 4th pin would be burned.

I don't have that issue with USB-C. But I do feel that the lightning receiver is less fragile over the USB-C one. Removing lint from a USB-C receiver is harder.

There was also a separate issue. Apple until recently had always used this type of plastic that easily degrades and certain peoples skin oil (mine included) causes the plastic to just dissolve. Turns yellow then brittle and then just comes apart. But that's not really related to lightning.
