I consider doing individual degrees have advantage if you are sincere and ready to work hard.
For example if you are get into IITs for M.Tech you can target few of the top universities in the world for PhD. If you are not able to make it IITs for M.Tech integrated degree have a higher advantage.
Instead of an integrated PhD degree I would recommend you directly try PhD degree from IITs. Refer to below post for more details.
