It's noticeable if you use the upper regions of the rev band regularly ... it's a gain of 5 - 6bhp over the Slip-On installation. Also, the motor picks up revs quicker from about 5 - 6k rpm and up.
As for worth it, that depends on you. It takes me almost as long to do an upgrade to Full Monty as doing one from scratch. A new jet kit is required along with the air filter, too, so there's not much price difference.
For those wondering which option to choose from the outset, it's a personal choice based on how you ride etc but I advise against going for Slip-On first thinking to upgrade later.
To give an idea of the gains from each option, here's a thread on a Full Monty-configured Gen 1:

Contrast this with Ivan's dyno charts including the ones showing the Slip-On kit with aftermarket end can (third graph from the top):
