The La Sportiva Stratos will be left out of the review as it wont be available this year.
In the beginning there was the Scarpa F1

For those used to "regular" AT boots the F1 will feel short and soft. With practice people find it's not long until the boot begins to feel normal and enables the skier to attack 95% of the terrain they would while wearing their stiffest boot. Aside from being lighter than a standard AT boot, the F1 has two major advantages that make it a great choice for racing. One, the large lever on the rear of the boot enables the skier to switch from walk to ski mode while it simultaneously tightens the cuff around your leg. It makes transitions faster and smoother. Two, the boot has bellows in the forefoot just like a telemark boot, but yes, it's an AT boot. The bellows allow the boot to walk in a much more natural fashion. When skinning on low angle terrain a skier can keep the ball of his foot on the ski much like a nordic skier does in classic technique. Thus, the skier is able to generate more power. When one must briefly skin downhill the bellows allow far more control compared to a boot that doesn't flex because the skier can keep the ball of the foot on the ski. Walking around in F1s is great. The bellows and the paltry weight make the boot feel more like a sneaker than a ski boot. The original F1 is a great choice for people who do some racing, but would still like to use the boot on their other randonee set ups.
The Scarpa F1 Race

The F1 Carbon

New this year is Dynafit's DyNA

Pierre Gignoux XP444

The XP 444 by Pierre Gignoux is by far the lightest boot on the market at 444g. That's the shell only. If you include Pierre's 140g liner, which is sold separately, the boot comes to 584g. Not surprisingly, that liner is also the lightest on the market. How are these boots so much lighter? Primarily it's the fact that they are 100% carbon. But Pierre is also using a lighter sole than anyone else. The 444 is also the first boot to ever use dynafit fittings that aren't metal. They too, are carbon- Dynafit receiving holes shaped right into the carbon. Should be interesting to see how those hold up. Reviews I have heard from owners are that nothing comes even close for downhill power. The boot does not flex in the forefoot, which is actually better than a flexing boot on steeper skin tracks. The ski/walk mode lever will tighten the cuff for one-movement transitions. Weighing about two thirds of anything else reviewed here prompts one to ask, "Is there a downside?" Yes. First, carbon fiber may be the stiffest and lightest material out there, but it's also brittle. Many racers have expressed frustration about the XP's propensity to crack. I haven't yet heard of any catastrophic failures, more about rock punctures and quasi-repairable stress fractures. The only other negative is the price 1,300 Euro for the shell plus 100 Euro for the liner comes to $2,060.
My new theory is that the idle rich would make the best ski mountaineering racers. They have the money to buy all the best equipment. They have the money to hire personal trainers and nutritionists. They can afford to travel to whichever races they please. And with all that time on their hands they can train at unbelievable quantities. I foresee the world champions of the future arriving to their races in private helicopters.
Thought you may be interested to see this, a 3 min video from the skimo kit guru, Diego Amplatz, showing all the secrets of the new La Sportiva Stratos. This is not a boot, this is a machine, no wonder its selling for €1600, it makes the rest look so old fashioned.

The Stratos is apparently so advanced that a comprehensive video is necessary just to be able to put it on your feet:
