Even though nothing was at stakes, they say they had their hands full with dealing with the recovery and fighting tunnel vision.

What with a real unexpected alarm in a real aiplane with no previous briefing ?
And remember, the "certified" 737 was supposed to be hand trimmable at the time.

Only now do we know Boeing "autocertified" their airplanes, and there are suspicions of trim difficulties on the MAX as well as the NG.
“Nothing wrong with leaving full power on”. Why would a competent crew ever do that? With speed whistling through 250/300 kts you are obviously not stalling. ( easily confirmed by GS readout). Reduce power, pitch and power ( covered in your Type Rating) if ASI indications unreliable. Partial flap as required, no automatics due erroneous Stick Shaker, and manually fly a return circuit to land.
