Hi Sri,
If you are willing to have the comparison for both the products for the perspective of SAP Applications then keep in mind that for MS SQL Server 2014 to get certified for SAP it may take time. Wherein for SAP HANA almost all SAP Applications are now available to port on SAP HANA.
SAP HANA is a revolutionary product and has been built from scratch following "in-memory database technology" wherein other vendors are trying to follow the approach given the technology is being adopted rapidly in the market.
For SAP HANA you can search all relevant documents in this space itself. Please find the link below for various requirements regarding MS SQL 2014:
