Reloaded and Ultra Edition Updates

I want to purchase Nero Ultra Edition and have a question regarding the updates on the Nero site;

Very few retailers on the web currently carry “Reloaded” ver 6.6, while many of them have the “Ultra Edition” ver 6.3. In almost all cases, the Ultra Edition is less expensive in addition to many sites offering a rebate for this version.

If I were to purchase The Ultra Edition and then update it from the Nero site am I going to end up with the same versions of all the components that are in ver 6.6 which comprise the Reloaded edition ? Or are there other significant differences between these two versions. In other words are there any compelling reasons why I shouldn’t get the Ultra Edition instead of the Reloaded edition.

Thanks for any insights and advice - Happy Holidays to All.
