 Parallel() is faster, I suggest your read this article (everything is of interest, but for your specific example, you may jump to Tasks return "hot").
Now let's break it down:

The await keyword serves to halt the code until the task is completed,
  but doesn't actually start it.

In your example, NotParallel() will take longer because your Tasks execute sequentially, one after the other. As the article explains:

This is due to the tasks being awaited inline.

In Parallel() however...

the tasks now run in parallel. This is due to the fact that all [tasks]
  are started before all [tasks] are subsequently awaited, again, because
  they return hot.

About 'hot' tasks
I suggest your read the following: Task-based Asynchronous Pattern (TAP)
The Task Status section is of interest here to understand the concepts of cold and hot tasks:

Tasks that are created by the public Task constructors are referred to as cold tasks, because they begin their life cycle in the non-scheduled Created state and are scheduled only when Start is called on these instances.
All other tasks begin their life cycle in a hot state, which means that the asynchronous operations they represent have already been initiated
