Ok sorry! I haven't used it myself, so I'm more familiar with how Google Photos handles things.

From what I've seen of iCloud Photos I just like Google Photos more anyway. The Assistant is pretty fantastic. It's also really easy to create albums to share with other people, and others can collaborate on albums. It's also cross-platform so my wife and I were both able to use it when I was on an Android phone.

Remember, I'm an iPhone user now but it's going to take quite a lot to get me to switch to Apple services!
