Caveat emptor: The direct drive is a totally different feel than that of a chain drive pedal. See if you could borrow one to test it out - that way, you'll know if you would be satisfied with the Axis or Trick for the longer haul. Both are extremely solid pedals, but as stated earlier, if the Trick had a factory setting (read: already 'dialed in' or a reference point, like the other pedals on the market), then it would be a really, really great pedal. In terms of engineering, the Trick tops the Axis from that aspect. I would say that Trick also has the edge on durability - well, at least from the materials that are used to make the Trick Pro 1-V.
The Iron Cobras... Well... We have the chrome model at our church, and it is not the best of pedals, but it is not the worst of pedals. I know that my commentary on the P900 cam is ambivalent, but that's the best way that I could describe it.
I thought that you were a Sonor guy. Go ahead and get the Giant Step if you are considering the Trick (they have a close price point).
