Hi jpak19,
That’s a very broad question and much too general to give any kind of meaningful or specific answer because it would depend on the specifics of the two mattresses you are comparing and on all the other parts of your personal value equation that are most important to you.
There is more information about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses in terms of suitability, durability, and “value”.
There is also more about the “one choice fits all” mattresses such as Tuft & Needle, Casper, and Leesa in post #3 here.
Lower quality materials and less durable materials can feel the same as higher quality more durable materials in a showroom or when a mattress is new … they just don’t maintain their original properties and their comfort and support for as long and will need to be replaced more quickly.
You certainly made a good quality/value choice … and congratulations on your new mattress
