One other reason to recommend SEO friendly URLs is that the users find it easy to remember and type the address of even an inner page on the browser’s address bar and whenever the user makes a copy/paste action, the URL simply represents what the page is about.
It is strongly recommended to use hyphen to separate two words in a URL. Underscores are not considered to be search engine friendly due to the reason that two words separated using underscore will be considered as two different words whereas it will stay combined though separated by a hyphen.
