Hello Anil

IIIT Dharwad will teach you more because it has more courses compared to IIIT Pune and both are rated equally good for faculty,placements and campus ,IIIT Dhawrad CSE fees if 6.30 lakh for 4 years whereas IIIT Pune ECE has 5.50 lakh for 4 years, IIIT Dharwad infrastructure is way better than IIIT Pune but it is said that food of IIIT Dharwad is not that good for both the  IIIT's the average placement lies around 5 lakh per annum and the highest for Pune was around 9 Lakhs per annum for a CSE student in B.Tech . I will attach a link where you can compare more colleges yourself and look at it yourself and then make a judgement yourself
