IMO it's not a question of better but which approach appeals to their potential customers. I doubt very much a designer or anyone else could tell whether an analog crossover has been replaced with digital if the digital is programmed to mimic the original analog. Of course there will be no peaking.
This is much harder than it sounds because the high resistance and impedance of an analog crossover is not easily simulated in DSP because of the complex electromechanical interactions including with air.
DSP is far better for the crossover, equalization, time alignment, etc. but ideally like Kii does you want an amplifier designed for the application as well.
