Having worked with several systems using both modules and micro services I would say that using modules is the way to go from a debugging and understandability perspective, so modules are a more productive method.

However micro services can still be valid but to me they are actually “developer UI” and should only be used when services have to be shared between developers who don’t know each other. For example a public API will almost always be an API with a micro service behind it
