- simple is probably the best place to start. It's a simple ARM template that is a good starting point for CLI deployments or customization.
- marketplace is the template used in the Neo4j Google Cloud Marketplace listing. It's easiest to deploy that template directly from the Google Cloud Marketplace here. The template has some Marketplace specific variables in it. If deploying outside the marketplace, you probably want to use simple instead.
