OK, so the main takeaway for me for example would be that if I want write lambdas in Go (because it's awesome), then GCP would be better choice for me.

But anyway, I'm not too current when it comes to lambdas. Are they compiled everytime when cold started, or is a compiled binary stored in some sort of image?

They are compiled during the deploy process, with the binary or code + deps (for JS etc) stored on S3 and loaded on demand. This counts as part of the cold boot time.
