hey there!

Both of the courses that you have mentioned above are entirely different. One is related with engineering aspects and the other with research aspects in any one specified subject. It is upto you in deciding between these two.In the current scenario I would suggest you to go for the dual degree in any of the IISER's since there are more value and opportunities existing there now when compared to Btech EEE in CET. The number of passouts from IISER's are also a huge factor since it has only limitted vaccancies a small amout of IISER students come out every year but in the case of other numerous passouts are featuring every year.
