ky - I'm lucky to have several independent rollers and a small 'one-store factory' near me, and have sampled fresh rolled cigars many times. They do have a different flavor than aged ones, but as to whether that is better or not is largely a matter of personal taste.
My experience echoes CL's comment, finding that at some point after they're rolled (roughly several weeks) they begin a maturing process (fermentation?), and are then best left in the humidor for 6 to 18 months (more or less).
With all the great deals around today, however, I am hard-pressed to justify the premium cost they command in my area. My best advice would be to try some for yourself, smoking some 'green' and aging some in your 'dor in order to see if they tickle your fancy.
