Which is more popular among people - coke or pepsi ?

For me,i prefer coke than pepsi because i feel it has a real and tasty taste.I like original coke taste and can drink it more.Coke has a good taste than pepsi and pepsi seem like not have real cola in their drink.So,i prefer coke than pepsi and seldom buy pepsi because i dont like it taste too much.If you try to drink coke and pepsi,and make comeparison then you will find why i choose coke than pepsi.Thank you and have a nice day.
