It is well suited in scenarios like you wants to track objects and surface in the plane. Image recognization at multiple targets is one of the very good functionalities of EasyAR. And if you want to render 3d objects in your mobile application then it's well suited. It is free too so you can create applications at minimal costs.
It is well suited for small objects in home/office or familiar surroundings to anchor Augmented Reality Objects. It works well for most e-commerce use cases, travel use cases, games, etc. It is not well suited where depth occlusion is the primary use case or human body anchoring is required or even for large-scale AR use cases.
EasyAr is free and there is no watermark on the output of it. It's easy to use and some features like multiple targeting in images and object and surface tracking help you to achieve what you want.
Vuforia Engine has limited functionalities compared to ARCore. It has image-based detection and augmentation which requires users to have the anchor image with them for the augmentation to properly occur. ARCore solves that and it's one step less to reach the user and really convince them to try it.
