Yes -- but only a minor difference. The GM Seed locks your iPhone into a "development mode" which prevents it from having it's firmware ever downgraded. The firmware that will be released at midnight will be identical, except for this lock.
Considering there are reports that the iPhone OS 3.0 update makes the 3G very sluggish, I'd steer away from the GM Seed since then you'll no longer have the choice to downgrade.

Since we're hours away from the official release, it's best to just stick it out instead of installing the GM. Is the risk really worth it, just to shave off a few hours from the release time?
antonioj is correct, however i think one of the issues was you couldnt downgrade the baseband back (only really a problem if you intend to unlock), not sure if this will affect how the phone runs with a newer baseband than main firmware

My 3G is not in development mode and is not sluggish, and I've been running 3.0 since last week.
Apple warned the developers at WWDC that installing the GM would lock their phone so that it cannot be downgraded. I'm assuming Apple wasn't making this up, but perhaps I assume to much?
The sluggish report comes from some posts I have read online, and also a friend whom I have the GM to that didn't want to wait. He doesn't follow iPhone stuff online and within a couple of hours, he told me his iPhone was running slow.
At this point, this is a moot discussion. There's no point to upgrade to GM today.
3.0 runs faster than 2.2.1 for me on the 3G. Having the GM allows me to have MMS and tethering with ATT already... I will not upgrade to the final release unless someone confirms that i will not lose MMS and tethering.
