How do you define "better?"
For charging its fine, as long as you aren't going for high power levels. In terms of data transfer, it simply can't support the data rates that usb-c can. If you want a simple, robust connector for moderate charging loads with moderate data transfer needs it is a great connector.
That's not opinion, just simple physics. Lightning has a lot fewer wires. Apple has managed to get base USB3 rates with a couple of devices, but nowhere close to the thunderbolt rates you can get with USB-C.
Having said that, for the vast majority of use cases, it is a great connector. Simple, idiot proof, and robust.
USB-C can do more things, though.
I've had 0 lightening cables break in any capacity.
While the USB-C cables I've had for Headphones, iPad, Asus Keyboard, Corsair Mouse, and a few other little things. I've had to replace 5 cables.
I love the idea of having 1 cable that I can use for everything. But no matter what anyone says, the lightning cable is superior in terms of physical connection.
I don't have anything against USB-C but its "click" factor varies a lot between cable/port manufacturers due to much wider tolerances/variances in manufacturing.
I saw the arc once with a cheap no-name cable. I'm guessing the cable tolerances on the conductor placements was off a little bit.
