The useful aspect of the memory cues is that the CDJ/XDJ has a down counter (bars) to the next mem cue upcoming. If Denon has same for hot cue it would be fine. Of course for everything else hot cues are superior to mem cues.
From what I can see in the manual, the Denon is only displaying the elapsed bars on the right side of the beatmeter - which is quite useless IMHO.
