I run a pair of Deadbolt 15's and a pair of Pivot 14's.
I love the DB 15's to death, they are super burly, the plastic parts are especially durable for plastic, and the sound they make when you click in is absolutely orgasmic. They do what bindings need to do, but somehow they just seem to do it so well. I am trying to find another pair and I'm super bummed they are discontinued and I'm too small to get the 18 din models that they still make, which even so are still kinda hard to find, and they are usually expensive as fuck.
I know you aren't asking about the Pivot 14's, but since they are so often recommended on here I like to use them as a comparison. I run these bindings on my floppy park skis and I think, even if it is a placebo, the super short mounting pattern does make a difference. And they just have a certain feel to them when you are pressing around with them that is very confidence inspiring, most claim that this is because of the heel design. However the pivot is a very old design, very, very old, kind of like how the Full Tilt/Raichle Flexon boots have aged. It is a good design, but you have to kind of wonder why nothing new has been tried when all the other designs have been updated. One of the biggest downfalls of the Pivot's are their absolute need for your heel to be totally devoid of snow or they are quite hard to get on, and they are kind of awkward to knock your boots against to get snow off in the first place. And finally when comparing the durability to the Deadbolt 15, the toe is absolutely atrocious, I know a few too many people who have had them explode. The Pivot 18 is a much more durable construction, but there are a lot of us who cant justify the higher din range.
All in all after the bullshit that I have just spewed, bindings really all do the same thing (for the most part) and are completely standardized in the most important factor, which is release values. The only differences are price, construction, and feel to a minute extent. Everyone has their own opinion on what bindings are best and you will get so many different answers from different skiers. The best bet is to try a few different pairs and find what you like best, and you will probably find that you stick with what you like for a long time as a skier.
tl;dr Deadbolt/peak/mojo 15 for lyfe
