I'm only syncing a few albums with selected items to my iOS 9 iPad, since it has only 64 GB of storage and I cannot sync the iCloud photo library to the iPad because I would be forced to use "Optimize Storage" which is horrible without a fast and affordable Wi-Fi. I am tired of having to watch the photos download slowly from iCloud over a cellular network and having to pay roaming fees to be able to access my photos. It is easier to sync a few folders with iTunes and store the photos in a full resolution, so I can show them off without having to wait for the download from iCloud.
