The serverless.com framework helps addressing #2,#3,#5. There are other frameworks that help addressing #1. Not sure what kind of compatibility or incompatibility do you have in mind for #4 - you could access RDS from Lambda if you really want.

I think "all the love" is related to the fact that you can enjoy the variety of AWS services (which does not exist to the same extent on GCP, at least yet), and integrate them together relatively easily. Also, from developer perspective, AWS documentation and SDKs are by far superior to those of GCP (at least from my experience).

GCP does have many advantages around specific features/services - but at large, AWS is (still) much more capable and mature.
