OK, I'll bite.
Depends on who you are. I am a shop owner/operator. I mechanically test hundreds of bindings a year, so I have a good feel for individual binding functionality, both new and after seasons of use. I also deal with lots of different types of skiers, some who value retention over everything else, some who want maximum safety, and many who just want something that "works" and is durable. I find it very important to qualify my customers and their individual needs and desires. You certainly don't want to put an older or beginner/intermediate skier on retention oriented bindings and the opposite is true for an aggressive skier.
Every binding manufacturer makes a product that will pass the mechanical function test, but it is obvious that the industry's testing procedure has many limitations and only tells a small part of the story. In general, here are my impressions, for whatever it's worth:
Ranking for Retention (from most retention oriented to least)
Rossignol (Look) FKS
Tyrolia Race Diagonal
Tyrolia Full Diagonal
Marker Squire/ Tour
Marker Biometric/ Twin Cam
Then pretty much flip the order for most release oriented. Doesn't mean that any of these are particularly "good" or "bad", just pick the one that fits your personal release/retention preferences. There is a lot of discussion about elastic travel, lateral stiffness, mounting base width, ramp angle and effect on ski flex. For 95%+ of skiers, there will be little noticable difference, and for the most part it is marketing hokum. The one factor that is important to skiers of all levels is stand height. The current conventional thinking is that more height is preferable for carving and precision on groomed/hard snow and less stand height is better for off-piste and freestyle skiing. Personally, I don't like the more retention oriented bindings, and avoid skiing with them as much as possible. I am a big guy (230#) and ski fast and aggressively, my binding preference is the Marker Biometric/Twin Cam models, followed closely by the Tyrolia Race Diagonal models. These are, by far, the most consistent on the test bench, both new and used and have worked well for me and my customers for years. The Marker Twin Cam/Biometric models have a bad name (especially here and on TGR) as prone to pre-release, I think that this is overblown and BS, but each to his own. I also am not a fan of the current trend of manufacturers making bindings that are cheaper to produce at the expense of safety/performance features and long term durability.
