I just upgraded from 2013 to 2014 edition, and so far, I'm impressed!
It's noticeably significantly faster than the 2013 edition, especially when it comes to scanning and loading web pages. It scanned my entire drive in about half the time as the 2013 edition.
Looks like Norton Internet security 2014 has better multithreading support than it's predecessor (which is probably where the speed improvements came from), as I noticed there was more CPU activity during scans. Norton also claims to have improved the Sonar feature in the 2014 edition to be better against zero day threats, and the repair capability should Windows files become infected.
