Which is better: SD or CF memory card for 5D Mark IV?

Re: This highlights an important point.

I remember reading that the controller for the memory card is part of (built into) the CF card, but not the SD.  The controller for SD cards is in the device, not the card.  That used to be the reason CF cards were faster and cleared more quickly.

Not sure if this is still the case.
