The -10 neither has MCAS or door plugs (might be the best one out the bunch tbh). If Delta pilots are going to be flying it without hesitation, then I have no hesitation of being a passenger. Unless they are having a mental break, no one is going to work on something they believe is unsafe.
The MAX has a tainted rep from MCAS (rightfully so), but this current issue is a QC one and imho has zero to do with the actual aircraft; other than it being the current production model. Could have easily been a 739, if those were still in production and Spirit Aerospace was slacking. Boeing will take the full blame, regardless of which subcontractor caused the issue and rectify it.
No different to me than continuing to use Quakers Oats (insert any company that has had product issues) in the future, after their own qc problem this week.
