wheelsright,

But do you think that it is possible to use electric trim to counteract MCAS before using the cut-out switches?’
Overall, and biased by the accident outcome, I doubt that nose up trim would have been effective, particularly when considering time of recognition, realisation, and action.
Continued debate considers if trim would / was enabled to override MCAS.
Then, the erroneous rate / power of MCAS design would out perform trim by 9 sec down to 3 sec up.
Also, there is debate and interpretation if trim is restricted due to design (EASA questions) and further if the aerodynamic forces restrict nose up motion - tail / elevator interaction.
Then the above must consider the pilots perception of the situation, the need for trim and the extent of trim required in very stressful, surprising, and demanding conditions.
All that must be confined to history. Whatever is changed in the MCAS operation it must not be able to mis trim the aircraft to extreme.
As for judgement of crew performance, consider

Crews either fail to understand the situation, HF - thus choose the incorrect procedure
Or with correct understanding, the incorrect procedure is chosen - HF (or procedure is not available - documentation, training, novel failures)
