I like them both and even have a guitar with a baked maple neck, which I like a lot. Very stable--which can be an important consideration if you're using highly figured maple in necks, I have been told. Supposedly, very flamy necks are not the most stable, though perhaps the laminations would help with this. I'm no luthier, so who knows.
But seriously, we're talking about the Dead here. How can you go with anything other than "baked?"
