I think it depends what you are looking for in the product. So many these days just sort by date, following Photos' lead. Aperture was great because you could sort photos by album, and more importantly, sync to your iphone easily. There are tons of great photo editing apps out there equal to Aperture, but nothing with the sorting capability and syncing capability that Aperture had. Aperture itself is sadly quite buggy and slow these days, making it an unattractive option. I think there are a lot of people (myself included) who would happily pay for an Aperture 4.
Yes you can put photos into albums, but you can't see which photos are not in albums and you can't stack photos. I used to use it for taking photos of cakes, several of each cake with the best shot stacked at the top. Because they are taken at different times, I don't want to see them in a chronology of my normal pics, I wanted them separated. Now I just see 5 pictures of each cake and can't remember which was the one chosen for publication etc. and can't easily separate them from my other pics.
I guess each person has their own intentions for a photo program. It's just a shame that Aperture did such a great job and then they stopped it, and no one has brought anything out that compares, at least for what I use it for.
