1970's comics are pretty iconic in their art style. there doesn't seem to be a very large middle ground of realistic versus a few abstract/cartoon style. so you've got comics like the peanuts where mostly everybody is made of a few simple shapes and than you have something like prince valient or flash gordon or dick tracy where everything's pretty realistic despite a few artistic choices here and there. the story telling differs greatly from each other as well.

peanuts tends to be very episodic with simple punch lines and jokes so there style lends to there need to an easy storyline



meanwhile a comic like dick tracy had over arching comic elements that  could last an entire issue. overall I appreicate both types of comic for there diversity in delivery and story.
