I have used flickr and Google photos, but Snapsboard app is miles ahead of both these app from top software companies. I mostly used their iphone app. Sometimes I have used this app on my laptop. You do not need to install any software on laptop. Uploading of 100's of photos and videos to snapsboard is very fast as app uploads 5 files together.
I like option to view single or multiple photos on my home page. I must say they need to improve musical collage and photo editing options.
