The difference is MCAS.
from this SLF- a.00002 bit of logic

Even without an AOA no compare light- on the NG would as I understand it have only a WTF effect and with maybe a slight bobble nothing much else

But with MCAS - again in my opinion- with that light added to the normal events with fubar AOA- and not knowing of HAL - the results would not have changed. One could argue a change in probability - but the smoking hole would be the same.

Obviously- there is a bit more than just MCAS and disagree ight- overloaded computer- and the 3 second superman response plus the inop manual trim need to be accomodated
