My vote would have to go to the MT Option 2. I did some serious investigating before purchasing mine. The reasons I like mine are as follow: (1) Ulu like blade, best all around, IMHO, effective at slashing, skinning, food preparation (2) best steel of the bunch, 154CM, that has been through all of MT"s usual processes (3) Boron Carbide finish, that will last and last. None of the others offer this (4) Best over all asthetics, IMHO, carbon fiber, translucent black coat, bead blasted SS lock side handle.
It is a bit thicker, but I find that it carries extremely well in most watch pockets on blue jeans. If I must carry it in my wallet, it gives me a good excuse to clean out old business cards, crappy family pics, etc., to make up for the added thickness. I also think that if this was the only knife you had in a survival situation, heaven forbid, it would be the best overall, given its comfortable handle and blade shape. These are just my opinions.
