What exactly is the metric for "best" here?

I consider MS's record under Nadella to be a mixed bag. Azure is probably Nadella's biggest success, but it's hard to come up with any other significant market in which MS has excelled under Nadella where they were not previously dominant.

From a user perspective, many MS products I use have improved and many have changed in ways I would consider to be detrimental. VS Code is probably the only new MS product that I've started using regularly - and I'd only consider it to be a minor improvement over Sublime Text for my use cases.
