> AWS has more services, but a lot of those are of dubious quality.

Being cynical AWS has more services because many of those are deliberately siloed in order to create a separate billing item, i.e.:

"You want to use AWS Foo ...great, welcome to AWS ! But unless you want to re-invent the wheel re-programming the standard workflow, you should really use AWS Bar and AWS Baz alongside it. Dontcha' like all the cute names we've given them ? Here are all the price sheets, don't forget to read the small print ... good luck figuring out how much it will cost you".
