Feedburner Smith Plugin no longer maintained

"The FeedSmith plugin , previously offered @ http://support.google.com/feedburner/answer/78483?hl=en ,is no longer maintained, and you should look for a replacement if you are currently using it. There are a number of options available on the WordPress Plugin Directory: http://wordpress.org/extend/plugins/search.php?q=feedburner "

I am looking for some advice on which is the most reliable plugin to replace feedsmith

Thanks
