Neither provides a DAM though. Photomator's asset management features are basically what Photos provides, which is far inferior to Aperture's DAM features. Many who miss Aperture aren't just lamenting the editing tools, they miss library organisation features that Photos simply doesn't offer.

Exactly! There are plenty of photo editors that could replace Aperture (and LR if you'd like), but DAM always seems to be the missing piece.

I'm using Photos DAM after leaving LR which I was forced to when Aperture went away.
