Have upu considered Google Photos? It meets pretty much all of your criteria with machine vision help there to help search and tag too. I'm invested in the Apple ecosystem and have all my pictures in iCloud, but have recently set Google Photos to sync all my 37K photos for free (if you allow compression) and am very happy with its features.

I did this because our home laptop died and we are now tablet and phone only in the house other than work computers. So my Mac/time Capsule/Backblaze backup strategy was thwarted. I didn't trust iCloud to be the only canonical copy of my photos, so now I'm using Google Photos as a cloud backup for the cloud.

I'll check that out, thanks! I have an entry level DSLR (18MP) so I was hesitant to Google Photos due to the compression, but the features look great. I didn't realize the machine vision for search and tagging was all included in the price/free for compressed pictures It's probably cheaper to pay for Google Drive space than pay for Lightroom, so it's probably worth it.

One followup question, since the browser is cloud-based, have you experienced significant latency viewing your photos? For example, when I use the Dropbox webapp it takes a couple to load thumbnail previews for a folder of 200ish photos while Finder on my Mac does it basically instantaneously.

I've found no lag when using Google photos, however it is mostly on the iDevices. When I do log in from a laptop I have never noticed any lag. This is in contrast to logging into iCloud photos from a browser which often has significant lag.

As my photos have been syncing with Google it has been automatically creating slide shows and collages. Each day I'm getting something new as it goes back in time. Pretty neat.
