Which entrance to yellowstone is best ?

I am making plans to go to the Yellowstone national park but i am little nervous and also excited because it will be my first time. I have heard so much about the biodiversity in the park along with the natural landscape. It had several entrances So can someone please suggest me that which entrance to the Yellow stone will be the best.
