I don't think it's the AFC is better than than the NFC. It's more like if you have a team that plays in AFC they have a tougher path to the Superbowl. Look at the Bills and Ravens of they make it they will have had to beat the other and more than likely the Chiefs. 
 
	 
 
	Meanwhile the Lions and Eagles have softer matchups. As the Rams and Commanders are both good but neither are really considered contenders. Feels like the top 5 are the Bills, Ravens, Chiefs, Eagles and Lions (in no order)
