The input element with a type of button has no default behavior, whereas the button element default behavior is to submit. 

• <button> will automatically submit, which can cause problems if you want to use a button in a form without it submitting. So it might be better to use <input type="button"> or <button type="button">. Without a type, button automatically receives a type of submit.

button able to contain img inside it, input can use image only as a css background

< input > must always be used inside a form. < button > can be used anywhere. Also, has a different context, in which you can use pseudo selectors :before and :after on CSS.

Theyre both HTML buttons, but unlike <button>, <input type=button> is always used inside a <form>.

The way text in a button is shown is also different. If you want a button that says Go, for example:

<button>Go</button> <form><input type="button" value="Go"></form>

Hope this helps.
