input type="submit" and button tag are they interchangeable? or if there is any difference then When to use input type="submit" and when button ?

And if there is no difference then why we have 2 tags for same purpose?

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

So for functionality only they're interchangeable!

(Note, type="submit" is the default for button)
