Hi diverellis,
Post #9 here has more information about the different ways that one mattress can “match” another.
The Rendevous has a different design than a “traditional” memory foam mattress so it would be more of a match based on perceived softness/firmness and level of support rather than having a similar “feel” to the Rhapsody because the top supersoft layer is a more resilient material than memory foam and it also has different materials and layering. The Regalis is more of a match in terms of design and with similar layering and would also have similar softness/firmness levels but it will also be a little different “feel” because the memory foam has different characteristics than the memory foam in the Rhapsody. Both use very good quality materials and are good value but they will be different from each other as well. If you tested the Rhapsody carefully and objectively for PPP then the odds are good that they will both be a suitable choice even though they will be different from each other. Neither of these mattresses have any obvious “weak links” in their design and construction.
When you are down to final choices between “good and good” … then it’s important to make sure that you have made some good comparisons between all the parts of your personal value equation that are most important to you. Neither of them would be a mistake in terms of quality or value but your confidence that they will be suitable for your specific needs and preferences based on the conversations you have had with each and the recourse you have after a purchase may all be important considerations that can help you decide which is the best “value” for you.
