does it worth to have a ToF sensor in phone ?

im interested in the ToF sensor and its possibilities, is it worth to buy the s20 ultra instead of 21 ultra just to have it (and save some money) ?

edit: i made my decision going for the s21 ultra because: 1.s20ultra is so hard to find here, specially the 256 gigs version. 2.the diffirence in money is almost nothing. 3.i really love that tof sensor but im not giving up a qhd 120hz, slower processor, worse camera, worse design and more 1 year of updates for it.

i may buy the s20ultra only if i had it new in package and 256 gigs of storage with a reasonable price.
