Can't speak to the A320, but the NG is antediluvian.
6-pack master caution old fashioned bright light in front of the flight crew, which frequently fails to light up without a firm tap or two. The overhead panel is almost identical to the original design, as any significant changes would need a new type rating.
Bleed air, and air conditioning particularly suffer from poor ergonomics and are easy to misconfigure. I understand the 737MAX is going to be substantially similar.
