Cloud for me as well.
I do have unlimited data but I don't have the photos backup over my LTE. I have it set to backup to Google when on wifi and the phone is charging. That way it does it once a night. No strain on my battery while I'm out and about taking photos and they backup automatically.
Y'all must have unlimited data to back up all your photos on the cloud while taking pictures.
I have a Fujifilm bridge camera with a 32 GB SD card, I don't think I've ever even considered making backups of my pics to a cloud storage while taking pictures. Usually I just pop my SD card into my computer and transfer the pics onto there.
Then I upload the pics I like onto imgur. I guess that's my cloud storage, haha.
