They could provide first hand descriptions of what was going on, and how hard it was to deal with it.

The
Indonesian preliminary report, para. 1.18.1, starting on pg. 19 (pg. 28 of PDF), has a narrative of the flight prior to the Lion Air accident.
The FDR data for that flight is plotted as Fig. 7 on pg. 16 (pg. 25 of PDF). The time scale is a bit odd (about 11 minutes 10 seconds per major division), and there are no numbers on most of the vertical axes.
The plot is also for the whole flight, although dealing with MCAS occurs over about 10 minutes very early in the climb. Hence the scale makes it hard to see the details of that portion.

Here are vertical velocity and altitude plots of ADS-B data for that flight made using

There are quite a few cycles of MCAS activation before the pilot cut out the stab trim, with one really steep descent. The bottom of that descent is about where the FO made the first PAN PAN call, per the narrative.
