Age.

Seriously though, that's a big question. Can you narrow it down a bit?  
If you really do want to know all the differences I suggest you google:

site:cisco.com 12.2sx release notes

...and spend an hour poring over the SX release notes, which document in 
great detail the new software and hardware features of each release.

But ignore SXD - there's no reason to be running it, it's years and 
filled with bugs.
