What do you use for sharing photos among your friends and family?

Google photos, create an album and just add people, I've done many times with many people and works great

Photos for iOS. In photos view, Select, check desired photos then tap share (box with arrow) and “copy iCloud link”. You can then paste that link into email, messenger or any other method you choose to communicate with family.

After a family trip or outing with your friends, there are lots of photos on everyone's phone. How do you share them with each other? Which android/ios app do you prefer?
