Why to prefer SSIS

Hi Experts,

Am working on a presentation and we have 2 teams one is presenting ETL solution on IBM Data Stage 8.5 am part of the MSBI team. I need to prepare a presentation where i need to list down why SSIS is better compared to IBM Data Stage 8.5. I know both of them are enterprise ETL tools but still there would be something where SSIS rules over Data stage.

Thanks & regards
