The only reason why "making it behave like other 737s" was even a goal to begin with was so that it wouldn't need to undergo more rigorous certification and pilots wouldn't have to undergo comprehensive training to get rated for the 737 MAX. This was very explicitly because pilots _didn't_ need to do that to get rated for the competing A320neo family, not because Airbus did absurd shenanigans to make it handle the same as the A320ceos, but because they weren't desperately holding on to a 1960s design that was amongst other things so low to the ground that the new engines being fitted to it couldn't actually fit. That has nothing to do with actual safety and everything to do with profit.
> The 737 has only one electric trim rate - on and off. It does not trim harder or faster than the autopilot trim or the thumb switch trim
Is there a reason you cut off the sentence you're quoting before the part that says "than human pilots could MANUALLY trim" and started talking about the electric trim rate instead?
Because that part of the sentence was written for a reason - the overwhelmingly more relevant reason why the manual trim wheel would not have saved them is that they would have had to crank it 15 times to trim just one degree (and they were much more than one degree out of trim, due to MCAS activating for five full seconds each time). Even if they weren't already overspeeding, it is highly doubtful that they would have won the battle to keep the aircraft in the air given their proximity to the ground + struggle to keep the nose above the horizon with two pilots versus one.
Also mind you by the time they entered the overspeed condition, they had already had the stick shaker going (due to the faulty AoA sensor, with no IAS disagree alert) and had had 2 MCAS activations to deal with, with the autothrottle failing to reduce the thrust to the climb detent because the very same faulty AoA sensor.
