Hi moolee,
You didn’t mention the size you are considering or whether it is mattress only or a set but it certainly uses good quality materials and appears to have very good value as well (assuming it’s new and not a floor model or a return). It would have the advantage that you could test it in person to confirm that it was suitable in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) so exchanging layers may not be as important to you.
It’s always great to have more options so that you can choose between “good and good” when you are making final choices but in the end only each person can decide which of the objective, subjective, and intangible factors that are part of every mattress purchase are most important to them. 
I’m looking forward to finding out what you end up choosing.
