py2neo, create a node ? two ways?

I am confused as what is the difference between below two ways to create a node ? It seems like the result is the same;

from py2neo import Graph
graph = Graph()

graph.cypher.execute("CREATE (a:Person {name:{N}})", {"N": "Alice"})  # a
graph.create( Node("Person",name="Alice"))  # b

Looking at the py2neo v3 documentation, it seems there's yet a third way to create a node.

First instantiate a Node object, as in

a = Node("Person",name="Alice")

then insert it in a subgraph (see py2neo types),

sg = Subgraph(a)

then create elements of this subgraph (Graph.create method):

graph.create(sg)

I understand that subgraph creation should however be preferred when creating numerous nodes and edges (a subgraph ...).

You're right, the result is exactly the same. Py2neo exposes two levels of API: a pure Cypher API (execute) and a simpler object-based API (Node). The latter is generally easier to get up and running with, the former is more comprehensive.
