Dolomites, West or East?

Hi!
I have really appreciated all the insight I have received from this site. Thank you everyone!
I have four nights to stay in the Dolomite's with my two teens.
Would appreciate assistance with deciding where to make my base, in the east or the west.
I want to sleep in one location the whole time so I do have to pack and unpack. I enjoy driving and am happy to drive an hour or so to sites. What is your recommendation?
Thank you so much!
