@dkarthik They are identical in output, I would go with the {!! !!} inside a blade template as it's shorter. All blade files get compiled and cached until modified too so no need to worry about any overhead. You can see them turned back into <?php echo if you see the cached output in storage/framework/views
The {{ do the same but also wrap the output in e() which itself is a helper function for htmlentities($value, ENT_QUOTES, 'UTF-8', false);
