Besides the obvious reasons (it’s smaller than usb and can work both angles of insertion unlike micro-usb), why is usb-c considered superior? I understand it’s more able to handle fast charging and better data transfer, but what are the mechanics behind that?

It’s smart.
Notice how old cables have USB A on one side and some version of USB B on the other, but now cables just have USB C on both sides? That’s because old USB was dumb. If the port is wired up to send power, it *will* send power regardless of how the other side is wired up. If you aren’t careful, you’ll send power to something that is also trying to send power and something ends up fried.
So industry standard was: USB A to send power, USB B to receive power. That way ordinary people physically cannot accidentally fry something.
But with the new USB standard, the two sides negotiate with each other. They figure out which way to send power first before actually fully sending it. So now you can have the same connector on both ends.
