Hi MrMattress and welcome to the Matteess Underground 
Any mattress you choose will be unique to those sleeping on it, based on their Stats (height, BMI, sleeping position(s) and any underlying health conditions) and their PPP (Posture and alignment, Pressure relief, and Personal preferences). Any ‘pros and cons’ list will be subjective to you, with your individual comfort and support needs.
As you can see by looking at the Mattress Durability Guidelines, latex is one of the most durable materials you can have in a mattress, though not everyone enjoys the feel of latex. Talalay latex has a very different feel from Dunlop latex as it’s considered ‘bouncier’ (the difference is like angel food cake compared to pound cake). As you don’t give any details on the mattress, your comfort on this mattress would depend on your Stats, and the thickness and firmness level of the Talalay comfort layer, as well as the other component layers in the mattress, and how they fit your body and sleep style.
The dual coil system, with innersprings and a microcoil layer, typically would have an additional comfort layer on top of the microcoils , of latex, memory foam, gel foam or polyfoam. For non latex foams, a good rule of thumb is to make sure any foam in a potential mattress has no more than an inch or so of lower grade foams (for memory foam no lower than 4 lbs/cuft for normal range weights) and if polyfoam is used, with at least 1.8 lbs/cuft density, just to ensure you have support.
A dual coil mattress has a very specific feel as compared to one with with just an innerspring support layer. I would take a look at the Mattress Specifications You Need To Know as well as this post from @Phoenix on comfort and support layers, to see how the components all work together. Also remember it can take anywhere from 4-6 weeks to adequately ‘break in’ a new mattress as well as your body acclimating itself to the mattress…it’s difficult to tell exactly how a mattress will feel over the long run after only spending a few minutes on it. This is why it’s important to consider all the aspects of your sleep and comfort needs before ‘taking the plunge’ on a new sleep system.
So in general, between the two mattresses you describe, what type of foam is on top of the microcoils or innersprings, and at what density and thickness, as well as the density and thickness of the other component layers, and how that matches your own body profile, and comfort and support needs, all need to be factored in for a good comparison. If you can provide your stats, and a couple specific mattresses you are considering, we can possibly assess how they may or may not work for your body type, needs, and preferences.
