Yeah, I use Google Photos too as a back up. iTunes just makes it easier to sync with all other apple devices as well.Even better use Google Photos, use your gmail account if you have on then use the app on your phone to upload photos to Google photos. This way it shows when and where the pictures videos was taken then free up space if you need to.
Then when you want to download the photo's to the pc login to your google photo's account and download to pc no wires needed.
you can use this method anywhere in the world to show your photo's to friends and family without them having to look at your phone.
