Yes, the new .pst format is more stable, less susceptible to corruption, and can grow to 33TB in size with Group Policy Object changes to set a higher limit that the default 20GB.
The real concern at those large sizes is backup. Users should also be made aware that performance can degrade if they have folders with thousands of items in them. More folders with fewer items will perform better that fewer folders with more items.
