I've also considered the turbo tent vs. a kodiak, and honestly, I tend towards the kodiak, too. The design simply works with the construction material's strengths, and tries to minimize their weaknesses better (IMO) than the turbo tent.
I'm leary of trusting the joints and struts on a turbo tent to be able to pivot and lock indefinitely. The kodiak relies on the the natural waterproofing action of the canvas, and also relies on the spring poles natural elasticity to maintain tension. A metal pole can bend and unbend indefinitely if done so within the materials "I'm not going to work harden" zone.
