You forgot to mention what Boeing didn't mention about a system on the aircraft that intervenes in a prestall condition that pilots and technicians didn't know the system existed. Yes it's a safe aircraft because of the reputation it has previously to the MAX redesign. Poor pilot training is unfair to say since the pilots did not have all the information available to them in a situation that occurred. You can't correct something not knowing what is going on and how your equipment is interacting with your QRH procedures to avoid a problem.While there are some genuine issues with the Max it overall is still a safe airplane
The research I’ve done on the two accidents the biggest issue was more about poor pilot training then actually the airplane being flawed.
Once there is a proper training on some of the new systems this will be as safe as any plane out there if not safer.
I would never hesitate to fly on one
