The question is in the title really. What is the difference between blog_info(‘stylesheet_url’) difference get_stylesheet_uri(), and if it’s a case that one is newer then which.
The codex says:
‘stylesheet_url’ – Returns the primary CSS (usually style.css) file URL of the active theme. Consider using get_stylesheet_uri() instead.
Actually
bloginfo( 'stylesheet_url) usesget_stylesheet_uri()function, so there is no difference.get_stylesheet_uri()is newer
