We are nowhere near being AWS' top customer, and have had absolutely incredible service from them.
Not only that, but we were proactively contacted by an AWS account team before we had even spent our first $100, and they spent many days providing guidance and support to our team before we even breached $1,000/month.
It may not be the norm, but my experience with Azure has been exactly the opposite. After having an (admittedly small) Azure presence for 4 years now, I'm going through the "front door" of their sales site to try to get an account person from them. So far, I recommend AWS over anyone else 100 times out of 100, 10 days a week.
