Dear Aspirant,
Both of the NITs are quite good, however, Rourkela has a higher ranking in NIRF 2019 ranking which is 16 and NIT Suratkal has 21. However, the ranking fluctuates with time and depending upon various factors, but under current scenarios, NIT Rourkela is a good option.
Hope this helps.
