Hello

IIIT Hyderabad is better than IIT Indore.

IIIT Hyderabad has more reputation and is better in terms of academics and competitive aspects.

In terms of syllabus, IIIT Hyderabad has an updated syllabus. For cse students, coding starts from year 1. You have to not study science, mechanics and drawing.

Every year, more students get selected to GSOC and get higher packages. Companies prefer IIIT Hyderabad

IIT indore will surely provide you IIT tag, but not better opportunities for your career.

Hope it helps
