Ranking

It is difficult to definitively state whether the B.Sc programme at ITM Institute of Design and Media (ITM-IDM), Andheri West is better than the one offered at Amity University Mumbai. However, we can compare some key parameters:

1. Faculty and Specializations Offered: ITM-IDM seems to have a more extensive range of focused design domain specializations like Fashion, Interior, Jewelry, Textile etc. The faculty is also specifically from design backgrounds. Amity faculty details are not clearly available.

2. Practical Exposure and Employability: ITM-IDM has extensive industry collaborations that allow good practical exposure through projects/internships during the B.Sc programme itself. This results in better employability. Less clarity of the same for Amity.  

3. Infrastructure: ITM-IDM has a dedicated design-focused infrastructure including studios, labs, etc. on its campus. Amity has a larger multi-discipline campus.

4. Cost and ROI: ITM-IDM is likely to be much more expensive in terms of course fees. But potential return on investment may be higher.

In summary - While Amity University has the advantage of being a full scale university, ITM-IDM specializes specifically in design domain and offers a focused practical oriented curriculum in that respect with industry exposures. This may give it an edge for a B.Sc in design.
