This is one of those questions you'll never get a definitive answer for. For starters, you should be the one teaching us the difference since you have SEB and non-SEB guitars!
But if there is a difference, it may be hard to detect and assess, depending on a million factors like e.g. the style of music - differences in tone development, the "envelope" of the vibration etc. tend to get lost the more distortion is applied etc.. You'd need to have a pretty scientific approach to measure differences and a reference guitar that's virtually identical to the test specimen except for the body construction and even then you may still not get conclusive results because they're still made of only coarsely predictable wood.
At the end - whether or not the wood has that divine spark or not is something that happens individually between the guitar and the player.
