“pip install --editable ./” vs “python setup.py develop”

Is there any significant difference between

pip install -e /path/to/mypackage
and the setuptools variant?

python /path/to/mypackage/setup.py develop

There is no big difference. 
With pip install -e
 for local projects, the "SomeProject.egg-info" directory is created relative to the project path. This is one advantage over just using setup.py develop, which creates the "egg-info" directly relative the current working directory.
