I've moved to pCloud for photos and I've found it to be a good alternative. One frustrating thing is that if you are cycling through your photos on the default pcloud app, they are usually slow to render which can be frustrating. Playing music on the app is also a little frustrating. It works, but it it's not an amazing UX. Other than that I am completely content with pCloud though, and I would recommend it.

One other thing to be made aware of is that the macOS ecosystem seems to be a little hostile towards pCloud and it seems to be fighting a never ending battle in order to the get the remote drive functioning reliably there. It works, but it can be a little annoying at times.
