recommended way to download images in python requests

I see that there are two ways to download images using python-reuqests.

1. Uisng PIL as stated in docs (https://requests.readthedocs.io/en/master/user/quickstart/#binary-response-content):

   from PIL import Image
   from io import BytesIO
   i = Image.open(BytesIO(r.content))
   

2. using streamed response content:

   r = requests.get(url, stream=True)
   with open(image_name, 'wb') as f:
       for chunk in r.iter_content():
           f.write(chunk)
   

Which is the recommended wya to download images however? both have its merits I suyppose, and I was wondering what is the optimal approach.
