The difference is in the material.
It's strength, esthetic and durability.
Zirconia crowns are copy milled. made from a monolithic block. it's a recent advancement. It has good strength and takes stress very well.
Normal crowns are porcelain fused to metal. If done properly there won't be much difference. Side effects only if crown preparation is not proper or there is a fabrication error.
Choose which ever suits your budget.
