One thing to consider on the SS - how annoyed will you be by scratches? Personally, I’m very annoyed by them. I buff them out with a metal polishing cloth every 6 months or so, but this was never an issue when I had aluminium. Presumably the scratches were still there, but the brushed finish disguised them. I’ll probably go back to aluminium for the S8.
Sorry - this is a duplicate post. It told me the post was gone, so I reposted then it appeared. Weird.
