So Daymaker sent me some adapters about a year and a half ago, and I have been majorly slack with getting a review up. That's partly because I still don't tour that often, so it's taken me this long to get much use out of them. I have used a Salomon Guardian (and a Duke once) as my main reference point for frames (also, tried pins once but it doesn't sound like you'll be using those, at least at first). I would love to test the SHIFT but like you, do not generally use boots with pins (that's something I'm hoping to figure out this winter).
All that said, there are definitely positives and negatives to both Daymakers and frame bindings.
On the downhill there is a clear winner for me, the Daymaker. You get to ride your regular binding and to me that is most comfortable. The Guardian and Duke both ski fine on the downhill, but I don't love the higher stack height, and they don't feel quite as secure/predictable to me (that could well be mostly in my head, but I've had the odd weird release, especially jibbing).
On the uphill leg both have positives and negatives. I'm far from a touring expert but my impression is that the walking motion of the Daymaker is more comfortable. On frame bindings I've tended to get sore hips from the slightly uncomfortable hinge point, and I didn't get that with the Daymaker. However the stack height on the Daymaker is really high, and I felt less secure on steeper terrain, as my connection to the ski felt less direct/close. Flipping between the different riser modes on the Daymaker is also a pain, and much easier to do with a pole on the Guardian in my opinion. However, the Daymaker offers more different angle options so again, mixed comparison.
To me though the most major difference is the transition between modes. Daymakers are a bit of a pain in the ass to get on and off. You have to clip the binding on to your boot first, then click into the binding. It might not seem like much but they are kind of fiddly to get on the boot in the first place, especially at first, and if you're doing a tour that involves multiple mode changes, the fiddliness does get old pretty fast. It's also an added complication if you are trying to change mode in an exposed or awkward spot. By contrast, with the Guardian you can change mode without taking your ski off. And while, I haven't mastered taking off skins with my skis still on, that is still a useful option to have in sketchy terrain/when traversing etc. Frames are so much easier to just click into on the fly that on trips that involved a lot of switching or having to take skis off and go scramble over some rocks, I've found them preferable.
I do prefer the Daymakers for both the comfort of touring mode itself, and on the downhill leg. I've also found them to hold up durability wise with no issue whatsoever. I'd definitely put up with the fiddly riser heights for that comfort, however I have been on trips where I really would have preferred the simplicity of a frame binding when it comes to changing mode. To me though it sounds like you'll mostly be doing some short backcountry tours that would likely only involve minimal mode changes. And that most of your ski days would be resort based without the need for touring bindings at all. And for that, I'd say the Daymaker with one of those bindings (Attack 13 is my personal preference of those) would be definitely the better option because most of the time, you're just skiing your regular binding.
