No, No, the 'friendly discussion' is that:

The Z-100 is as fast at 5MHz and faster at 8MHz than the AT because the AT
requires one memory wait state and was designed and firmware programmed
by IBM and the Z-100 doesn't.

The WS on memory boards as you mentioned is a common problem with mem
boards.  It is usually the fault of slow decoders and buffers on the
board addressing logic rather that the speed of the memory ICs.  Replacing
the 74LS240/244 and others with 74ALS or 74S series TTL usually corrects
the problem
