According to me, B.Tech (Electrical engineering) from IIT Roorkee is a better option due to the following reasons:

• B.Tech electrical engineering is a 4 year program while dual degree (electrical engineering) is a five year program. This means that choosing IIT Roorkee will help you enter the workforce earlier.

• The B.Tech curriculum focuses equally on theoretical and practical learning. This will prepare you for industry roles. 

On the other hand, the dual degree curriculum gives more importance to research and specialisation in electrical engineering.

• Here are the 2023 placement figures for IIT Roorkee and IIT KGP:

Unfortunately, the branch-wise placements are not available for either of these IITs. 

I would recommend you choose B.Tech Electrical at IIT Roorkee over Dual Degree in Electrical at IIT KGP due to the above reasons.
