mechanically, the lightning connector itself is simpler/better than the usb-c one. it's more robust and it's easier to clean -- i'm always amazed where crud can end up on anything electronic, and how much of it.
on all the cables i've used, though, the usb-c "grab", its shell, what you pinch between your fingers to manipulate the connector is superior to the lightning one because it's just a little bit bigger. too often, it's a b*tch to unplug a cable from my ipad because it's just a little bit too small. never had that problem with my pixel phones.
like i said, the lightning connector uses a mechanically simpler design and i wonder if it could have been used to transfer more power through it, at usb-c levels. i still think it could have overcome "the next usb", as in reversable, no-fuss connector.
usb has turned into a mess, with a plethora of various connectors and "levels" (i mean, "USB 3.2 Gen 2x2", really?), with the added possibility of frying your electronics if you use the wrong brand of usb-c cable. and don't get me started with driver support. it's no longer "just use it, don't have to think about it" like in the usb2 days.
eventually, the mess will be cleared up and you won't risk frying your expensive electronics (amongst other things), but until then, i'll be unhappy using anything usb-c.
