The <!DOCTYPE> declaration is NOT case sensitive. However, the simplest and most reliable doctype declaration to use is the one defined in HTML5: <!DOCTYPE html>

HTML is case insensitive. It means that you can use each of them. However I recommend you to use <!DOCTYPE html> and to type tags like <p></p> lowercase for a good practice.
