Which will be better SIT Tumkur ISE or IIIT Nagpur ECE?

SIT Tumkur is a decent choice. Both the ISC and CS branch faculties are very well established as compared to the other faculties in the college. The syllabus is also very well updated and is set according to industry standards.

A number of different companies hire students from a number of different branches with decent packages of INR 3 to 7 LPA. Many different companies like TCS, Accenture, Siemens, Bosch, Byjus, etc. visit the college annually.

Lastly, if you want a fair comparison, my advice to you would be to visit both colleges and get in touch with the departments, their students and seniors. You are basically going to invest 4 years of your life here.
