Tim, It depends on what kind of workload you're going to be running. In general, you would like to keep your guests on the small size. Given the fact that mainframe CPUs are on the slow side, if you've got systems that need 2 processors, Linux/390 might not be the right choice for the application. Defining 2 processors invokes the overhead associated with SMP, so you lose a fair amount there.
Essentially, scale horizontally (using multiple guests) if possible, and not vertically.
