Resolved iPhone 6s Factory Reset

[Helmsley]

I'd like to give my iPhone 6s a factory reset.

Would it be best to install iOS 11 first when it becomes available tomorrow, then do a factory reset?

I would wait until 11 is installed

Thank you.

Is there any difference resetting my iPhone via the settings versus doing it through iTunes?
