I cannot tell you how AMAZING it felt the first time I got a SaberForge saber in the mail that came with sound, I took out the kill key and pressed the ignition button and I basically had the biggest nerdgasm ever. Sometimes if I'm having a bad day I'll take out one of my SaberForge sabers and turn it on, then turn it off, turn it on, then turn it off, JUST to hear the incredible ignition sound erupt from the speakers with a blazing LED shining in my room. To me, the biggest part of a lightsaber replica is turning it on and hearing the iconic sound effects, so I couldn't imagine ever getting a warrior edition that doesn't have sound. But to each his own.
Regarding the Gladius and everyone having one, you may be interested in customizing your hilt with some vinyl designs or other unique modifiers to make it stand out, like what this guy did:

As for the Fury, I have one with the old 5W LED and neutrino soundboard, but I'm absolutely in love with the handle design and will definitely be upgrading it to a 12W in the near future. Here's a video review if you're interested:
