Which one best? snapchat vs Instagram stories

Both platforms provides the cool features in stories. Snapchat was the first who started this story idea. They have very cool features in filter, better than the Instagram story. Instagram have updated their story format with some unique stickers, GIF and other ideas. They have the unique level of audiences who promote the story format. 

For filters, Snapchat is very cool but Instagram have more extra features so I prefer Instagram stories over Snapchat.
