I suggest to rely on facts and figures. In doing so, I would rely on airsafe.com. They are of course familiar with the methodological issue that some of the respondents have raised, i.e. that an aircraft that is flying more often risks having more accidents. Thus, the airsafe statistics report fatal passenger events per million flights, see Plane crash rates by model.
The result is as follows (fatal crash rate per million flights):
Airbus 320 family (all models): 0.09
Boeing 737 (all models): 0.24
Boeing 737 MAX: 3.08
In other words: the Boeing 737 is 2.7 times more crash prone than the A320 family.
Since the original question enquired about the safety of the Boeing 737 MAX compared to the A320, here is the answer: The B737 MAX had 34.2 times more fatal crashes per million flights than the A320 family.
