Docker extensibility is common in the open-source faas projects but not in any(?) of the commercial serverless offerings (Google, Amazon or Microsoft).
Runtime support (upload code not a container) is more common in the commercial offerings that most of the Docker-based faas frameworks, which use a container as the packaging.
OpenWhisk is more flexible than most of the platforms with respect to packaging IMO (Wanna deploy code? Great. Prefer containers? Sure. Wanna use code and a custom image? No problem!)
Event support is more common in the commercial offerings (as they have cloud services for you to use), whereas the "faas" framework seem more bare bones. You'll have to configure event integration manually. Same goes for API gateways.
OpenWhisk supports numerous open-source event providers with a extensible API for integrating new providers. This is more complete that lots of the other projects in this respect.
Over time these features will become default in all projects but there does seem a split in focus between the commercial offerings and "faas" frameworks at the moment. I'm biased :) but I think OpenWhisk has a comparible feature set to Lambda (having been around for over two years) whilst still benefiting from the open-source docker story.
