Hi Srabon ,
Here are the benefits and limitations of both ,decide as per your environment and requirements
SharePoint Groups:
          Benefits – The definition and use of SharePoint Groups is under the control of the SharePoint administrators.  SharePoint is a more dynamic environment
where Sites and Lists are created for short term use by teams as part of a project.  SharePoint Groups provide the flexibility to be created when needed and then removed just as easily when the project is completed.
          Limitations – The scope of a SharePoint group is limited to a Site Collection.  So, if I want to give
access to a group of users to more than one SharePoint Site Collection, I need to create that group in each of the Site Collections.  If I do that, I end up having to manage membership across each of those SharePoint Groups separately.
Active Directory Groups:
Benefits – As the foundation of the operating system and Exchange, most companies are familiar with Active Directory Groups.  They are used as security groups for access to network devices
and other infrastructure and applications.  They are also used to manage distribution lists in Exchange. 
Limitations – Active Directory Group management (adding/removing users) is usually controlled by the Network group within IT.   Due to the impact
of these groups, IT departments usually have very strong controls and policies around membership requests and changes.  These controls make it difficult for the SharePoint administrators to be responsive to the dynamic nature of SharePoint – meeting the
needs of a collaborative use model.
