Mhh Maybe 
Like you say these are two opposite moderation styles and both have their disadvantages / advantages but moderation isnāt black and white like that. Thatās why in communities Iām in, theyāve all found their own moderation style to suit their needs since moderating shouldnāt be a full time policing role 
Like it says in Discoursesā FaQ:
āmoderators can be community facilitators, not just janitors or policeā.
If moderators are too laid back it could drive your members away for a few reasons such as a lack of policy/ disorganisation and action not being taken on problematic posts because its just ānot that badāā¦ leading to toxicity maybe? Just some thoughts.
But by the same token, āhyper vigilanceā can make people feel afraid to post which is what you donāt want in a community
