Can anyone send me document which show the difference between Toad DBA suite for oracle & Oracle enterprise manager?

There was a 3-part blog post last year on this topic by one of our Senior Product Managers.
You can find them here:
The blogs summarize the contents of a TechBrief on this very topic, and include a link to an older version of the document. We’ll try to get you a link to the latest TechBrief version.
