The IISc is ahead of the IITs in terms of teaching quality, laboratories, and student quality. No wonder that entry into them is so much harder than just cracking the JEE. However, it is well suited for research. If you’re thinking numbers and salary packages, you’d better go for the IITs.

IITs and IISc both are good. It's depends on your interest if you are interested in research you can go for IISc otherwise, you can choose IITs.

Both the institutes offer excellent faculty. Both have good Infrastructure and provide excellent placements.

Good Luck!!
