Shareaholic and sexybookmarks – same plugin or not?

I’ve been trying to rediscover a plugin that included a “You may also like” section below each post that I’d originally by accident when updating a site and its plugins, but didn’t leave enabled because there were some integration problems. So I searched for “Related posts” and found wordpress-23-related-posts-plugin which looked good but wasn’t the right one. Then I searched again for “You may also like” and found shareaholic, but I also found sexybookmarks. They both say the same thing:

Adds an attractive social bookmarking menu and related content widget to your posts, pages, index, or any combination of the three.

I’ve used both of these plugins before… when they were different. They’ve got different versions… I wonder how different they are? Shareaholic appears to have been forked from version 6.1.3.8 of sexybookmarks to create version 7.0.1.0 Huge update! The plugin has been completely re-written from the ground up to be faster, simpler to use.
