I agree, the slightly darker top is nice to my eye and gives it a fine head-start to the natural aging process of yellowing the guitar.

I think some of the issues that were out there with regards to coloring were things like "racing stripes" where there would be significantly darker stripes of darkened color an inch or more wide that would run up the tops, which many people disliked. It never really bothered me too much, personally.

I agree on the improved tonal characteristics - the reason I say "improves" in quotes is that this is entirely subjective. Some people are very sensitive about these types of proclamations for some reason. I believe it does make for better tone, which is why I have a guitar with torrification (red spruce top) being built currently. To my ear it is louder and more articulate than the same species of spruce that hasn't been torrified. As you've said, it's opened up right from the start rather than waiting years for the wood to change enough to create that open sound.

Of course when it comes to the tone of the top wood, besides the bracing (which is obviously unbelievable important), I believe that the finish matters a lot and as thin a nitro finish as possible is ideal. I've drank the kool-aid with regards to hide glue as well. At the very least, it makes a neck reset (dove tail, glued joint neck) or any other type of surgery easier in the future.
