I do not drink milk, so I cant say about which is better.

About The Starbucks question I feel that in the same way fast food chains have local menus, like how BK would have things that you would not see in US, Starbucks could be the same.
I found that Iced Americano was one of those items, it would come out different then what it would be in the US. For my taste at least, maybe others disagree.

I also feel like baristas can make or break the coffee. Depending on the barista you have does impact the taste of the coffee. Just my opinion.
