A comparison of Rb vapor cell standards vs Cs vapor cell standards? Or a general comparison why different kind of standards are built with Rb and Cs? For the former, there is a paper that has some of the details why Cs was choosen over Rb for the CSAC in one of the papers. (Which I currently cannot find...) For the latter, there is no easy answer and a lot come from technicalities (difference in handling) and what people were able to build. There are some fundamental differences in which elements get you what kind of stability for different kinds of atomic clocks, but I have seen very little on that and it's quite spread over various papers and books.
