If you feel that your bike is under sprung then yes the springs are a great idea. The emulators improve the damping action on the forks( mainly compression) and are more tunable to get what you want if you are willing to put the time in. Some guys have put the springs in and changed the oil level/weight and been happy as well.
Personally i have the full kit with emulators on both of mine and i'm very happy with the results. I put a lot of time and effort into testing on the front end and for me its paid off with a much better working fork. A lot more control from a damping perspective, less braking nose dive and much more compliant over small bumps.
