Eco Sleep - caliber or bolsa?

Hi, my wife and I are looking to upgrade our APM Queen Eco Sleep with #28 Medium Topper from 2017 to a king, and now see that bolsa coils are an option.

We like our current eco sleep medium with caliber coils well enough, but curious if the bolsa might actually fit our needs better. I am 6’1" about 205 lbs, she is 5’10" about 160lbs. She sleeps mostly back with some side, and I mostly side with some stomach.

What would you recommend for us? Thanks!
