2. Where better CMRR is required, the PA0FRI's differential amp has an edge over LZ1AQ's common base
I am not sure wether this proves true in general terms. The CMRR of the LZ1AQ type amplifier depends on the symmetry of the pcb-layout, the gain balance, the balance of the Push-Pull transformer and the performance of the common-mode choke (Balun) at the coaxial output.
