BizTalk Server has been around since 2000, and there has been a number of new product releases since then. It is a very mature platform with excellent enterprise integration capabilities. On the other hand, Logic Apps is a fairly recent edition to the Azure PaaS list.
Logic apps can be likened to a BizTalk orchestration but has a much easier learning curve, and you don't have the deployment hassle of a full BizTalk solution. Although Logic Apps and BizTalk Server are not functionally equivalent, they do have some similarities.
