I can only speak from my experience with the Morels, but for the price they are probably the best you can get. I would easily pay 200 to the morels. Haven't heard any of the other sets, but i'm very happy with my Morels. I actually liked them so much I wrote a review about them, not the best but it gets the job done. look in the reviews section and its there.
Just so you have a better idea of what you're looking at in sound when it comes to them.
I'm not dissing the other sets at all, just saying i'm very happy with the maximos.
