Hi slickvik,
Unfortunately it’s not possible to make specific suggestions or recommendations for someone else either for a mattress, a manufacturers/retailers, or a combination of materials or type of mattress because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort” or PPP (Posture and alignment, Pressure relief, and Personal preferences) or how a mattress will “feel” to you based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
The choice between different materials or components in a mattress or different types or categories of mattress is always a preference or budget choice rather than a “better/worse” choice (see this article). Every type or category of mattress has hundreds of different options and designs, some of which could be a perfect “match” for some people and some of which may be completely unsuitable for them to sleep on … even though they contain the same materials and components. In other words the specific design of a mattress and whether that specific design is a good match for you in terms of PPP is always more important than the type of materials and components inside the mattress.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here which which can help you make more meaningful quality/value comparisons between the mattresses they each carry in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists (based on all the parts of your personal value equation that are most important to you).
While I can’t speak to how comfortable a mattress may be for someone else or whether any specific mattress is a good match for someone else in terms of PPP or all their other criteria or parts of their personal value equation that are most important to them (these are all parts of a mattress purchase that only each person can decide for themselves) … the only recommendation that I do make is that once you are confident that a mattress would be comfortable for you to sleep on and is a good match for you in terms of PPP that you also make sure that it uses high quality and durable versions of the materials and components that you tend to prefer (see the quality/durability guidelines here) so that you have confirmed that there are no lower quality materials that would be a weak link in a mattress in terms of durability and the useful life of the mattress.
For those that have a history of choosing mattresses that are unsuitable for them to sleep on or that have a body type or health considerations that are more challenging that makes choosing the most suitable mattress more difficult or for those that for whatever reason are more uncertain about whether their choice is “right” for them then the options you have available after a purchase to fine tune the comfort or support of the mattress or to exchange or return the mattress or individual layers can become a much more important part of the “value” of a mattress purchase (any return/exchange policies are built into the cost of a mattress and the large majority of people that don’t return or exchange a mattress are the ones that pay for the small minority of people who do).
While I don’t have any personal experience on any of the mattresses you are considering … I can make a few comments about the generic materials they use in each of them. All of them are coil on coil mattresses so the main differences in their designs are the type of innerspring they use in the support core and the type and thickness of the foam materials they use in combination with the microcoils in the comfort layers. There is also more about the different types of innerspring support cores in this article and in post #10 here.

This uses memory foam and polyfoam comfort layers in addition to the microcoil on top of a Verticoil support system with foam edge support (which is an open offset “linked coil” innerspring)
[quote]Paris

The primary material difference in this mattress vs the London is that it doesn’t appear to have any memory foam in the comfort layers and only uses polyfoam in combination with the microcoil in the comfort layers. It also uses the Verticoil edge innerspring which uses coils instead of foam for edge support.
[quote]Bel Air
www.texasmattressmakers.com/bel-air-gel-...top-deluxe-mattress/[/quote]
This appears to use similar types of materials and components as the London in the comfort layers but it uses a pocket coil with foam edge support for the support core instead of a Verticoil innerspring.
[quote]River Oaks

This uses similar materials and components as the Bel Air except that the description indicates that it’s a little firmer than the Bel Air.
[quote]Santa Barbara

This appears to be fairly similar to the Paris and uses similar materials except it appears to be a little firmer.
Of course this is only about the general type of materials and components they are using in each mattress and doesn’t say anything about the quality/density or durability of each of the foam layers on top of the innerspring (which tend to be the weakest link in a mattress) or which of them is the best match for you in terms of PPP (which you can only know based on your own testing or personal experience).
Texas Mattress Makers typically uses high quality/density and durable materials in their mattresses but no matter which manufacturer you are purchasing from I would always make sure that you have the information you need to make an informed choice (see this article) so you can confirm that any mattress you are considering meets the quality/durability guidelines here.
