Hello Aspirant,
As we know that all the three institutions are well known and of great importance so it is little bit difficult to choose the best one out of them as all three are best ones.
Although if you want to have on campus placement in big MNCs like Google, Microsoft, Amazon and so on from CSE branch, so you should go for HBTU Kanpur. You will have great chances of exposure to above MNCs in HBTU Kanpur because in DTU and IIT Kota some lited companies use to visit for placement.
But if you are categorizing on any other parameter than you can go for any one of the asked institutions.
