Lightning is symmetric, Micro USB is not.

Lightning is smaller than USB-C.

Also from experience Lightning is a hell of a lot more robust than both.

I've witnessed at least 4 original Apple Lightining cables working with a device and not working with another one.

My biggest issue with Lightning is that it doesn't support HDMI. iPhones (and iPads) transmit an encoded stream to the Lighting to HDMI adapters which then get decoded and converted to HDMI by a chip in the adapter. It adds encoding artifacts and latency.
