I don't own one myself, but supposedly the SC700d is supposed to be extremely good. It features a quad-die LED (XHP 70.2), so output isn't too far off from multi-emitter lights.
At 2600 lumens, The SC700d's max output is lower than some multiemitter lights. However, where it really shines is runtime and efficiency. It can maintain almost 1000 lumens for nearly 2 hours. Very few other lights can do that. An Emisar D4 has a higher max output, but ramps down very fast and levels off within a couple minutes at 500 lumens.
Zebralight accomplishes this via Zebralight's extremely efficient drivers, coupled with the best heatsinking design of any similar-sized flashlight.
It should also be mentioned that multi-emitter lights tend to have a wide hotspot with little spill. The SC700d's beam pattern should look more like other traditional reflector lights with a distinct narrower hotspot plus lots of spill.
