Hi Idahodad.
Welcome to our forum. 
While both mattresses you are considering will be good quality/value and very durable options, the choice to purchase one over the other would be more connected with your own needs and preferences and with your own personal value equation and what is important to you.
Zoning systems of various types can sometimes be useful and worth considering for people that have more difficulty finding a mattress with the right “balance” between comfort/pressure relief (under the shoulders especially) and support/alignment/pressure (under the hips/pelvis especially) or who have more challenging circumstances or sensitivities, body types that are more difficult to “match” to a mattress, more complex medical issues, or who have a history of having more difficulty in finding a mattress that works well for them. Unless you have special requirements I wouldn’t get as caught up in the complexities of a zoned versus non-zoned pocketed coil innerspring unit. There is more about zoning in this article and in post #11 here and the additional posts it links to but once again the only way to know whether any specific mattress (zoned or otherwise) will be a good “match” for you in terms of PPP (Pressure relief, Pressure and alignment, and Personal Preferences) will be based on your own careful testing and/or your own personal experience. Both certainly can be appropriate for a majority of individuals, and each of the innerspring units will work together with the comfort layers of the mattress to provide an overall support and comfort, and nothing will be able to replace your own personal testing to see what combinations, if any, that you prefer.
Tufting or “bunching” of the material and attaching it to deeper layers of a mattress is used in different construction methods as a way of creating a certain comfort and also enhancing durability. It is most often used in traditional innerspring mattresses, like the ones that contain a majority of polyfoam in the comfort layers to enhance durability or … it is used in mattresses that contain very high-quality fibers as a way to help overcome the tendency of all natural fibers to compress and become firmer over time. In a component-style system such as the one offered by NestBedding…, mattress tufting would prohibit the layer removal and adjustments which is component style systems prized for. If you are looking for any after purchase customization then Nest would have the advantage of allowing for fine-tuning the layers to match certain comfort/support requirements where the layers can be reconfigured or replaced,
I don’t know how important tufting or zoning is to you but Nest recently reworked two of their popular lineups. (The hybrid you are looking at and the All Latex) This week they shipped the new models to all their showrooms across the country. And depending on where you live you might be able to go and test them. The new mattress specs for Nest Natural Hybrid Latex (thicker quilting 2" of Eco Flex foam quilted to 1.5") seem to better match your preference to be further away from the latex layer underneath. You can find the information about both the Natural and the Organic versions in Post #25 here.
I hope the information provided helps you out with your choice and I look forward to learn about your final decision and of course any other questions you might have along the way.
