That MAX actually improved the landing speed issues over the 737 NG -800 and -900 aircraft.

The 737-800/900 has a roll stability issue with landing flaps 40. The wings "wag" back and forth. For that reason, the airplanes are normally landed with Flaps 30 which adds 8 or 9 knots to the approach and landing speeds. The MAX, -8 and -9, have fixed this problem so flaps 40 are the normal landing flaps setting resulting in landing speeds which are 8 or 9 knots slower than the -800/-900.
