Maybe I was lucky and just had a string of good PFE’s, but my experience with MS support has been great.

I've found Azure support reasonable. It's still not an easy product to use overall compared to AWS but the support engineers have been very proactive and keen to jump on calls to fix stuff.

(thought better of this comment)

Making bad software in hopes to fix it later for a lot of money would never be a business model anybody can sustain for longer than a few years, let alone 2 decades which Microsoft managed to pull out through extraordinary effort.
