USB-C has for years now supported higher wattage power delivery, and higher data transfer speeds than lightning.
I can't speak to your experience, but from mine, the build of quality of Apple's own lightning cables was terrible. I owned two IPod Touch's over the course of about 6 years, and I basically went through one cable a year because they'd just disintegrate towards the ends of the cable or internally decapitate themselves. Didn't even need to break them, they'd break themselves.
Whereas in the 6+ years I've used phones with USB-C, only two of them have broken. One was because the cable got snagged under a chair and I pulled the USB-C end off not realising it was stuck, and the other one was my Mum breaking the USB-A end shoving it into a plug the wrong way. Both things that had nothing to do with the build quality of the cables. I still have every other one of my USB-C cables.
