It is only limited by the local infrastructure. i.e. want to charge faster? own a bigger / better battery bank, with bigger charging cables and a better car. DC -> DC (with some PWM / battery management) can also be slowed down (or use reduced amps) to best suit the moment. So if versatility is better, then DC to DC is again "better".

This is the scaled up equivalent of an external laptop AC/DC power brick. It’s faster because it’s supplying much, much more power. Multiple homes worth. Batteries need DC to charge and putting the transformer in the external fast charger means the one in the car itself only needs to be sized for lower power domestic charging.
