I have also moved to Photos. And hope it will be improved.
I am sticking with Apple software because of the many Apple devices I own, that need to be compatible with each other and kept in sync.
On the Mac Photos has been improved, and I sincerely hope that photos on iOS devices will again become a tool for managing a photo library too, and not just a tool for sharing image files.
An image file without metadata will pretty soon become a waste of storage, if we cannot add caption, titles, keywords and display them with the photo. The developer team thinks to believe, that we will know what a photo is about by simply looking at it and refuses to clutter up the display with text.
On iOS devices we have currently only two options to assign a meaning to it - we can dd the photo in an album and we can write something into the faces labels. But there is no way to search for the albums a photo is in to find the name of the album. And using the faces names as keywords will break the automatic face recognition.
