Interesting article. Personally, I like TenX, so this is the one I have been accumulating. However, as you say, there is room for more than one player, and the trustless aspect of TKN seems appealing.
I also share your dislike of MCO - for the same reasons! ;-)
TenX is a great product, I just don't see it as a good TRADE for the moment. However, it is definitely ahead of the game, in terms of having an actual product out and about.
Also, fuck MCO. :)
