Biggest functional difference is probably the angle retention system; one clicks into different angles, the other is just held by rubber tension.
For those who care, its also got a red light.
I found the Fenix adjustment to be finicky. The Zebralight's adjustment is smoother, and infinite, and sturdy. OP stated he wanted a simple interface, doubt he cares about a red light.

I never said that the Zebralight didn't use 18650s.
Then, what, exactly, is nonsense???
