It will depend on what you require from a digital assets management system.
Photos allows you to manage your photos and edited version in a lossless way. You have can create albums and smart albums, add keywords, titles, captions. The star ratings are not supported, there is only the "Favourite" heart, no color labels, no flags. No batch changing of metadata.
Not all EXIF tags are displayed.
Photos supports many of the adjustments that Aperture had, but you cannot brush them in locally, and you cannot define adjustment presets or metadata presets.
I will keep my main photo library in Aperture for the time being and wait for a few improvements to Photos.
