ECE at IIIT Allahabad started more recently i.e. 2006. So is the ece here comparable to that of NIT Calicut or BIT Mesra or NIT Nagpur?Please give me the preference order. (I am planning to do ms abroad so which amongst the above institutes should i prefer more?)

go for ec at IIIT A ...and it is far better than the colleges you mentioned because of the differnce between the qualities of the companies visiting IIIT A..the companies visiting MNNIT allahabad also usually visit IIIT A so you get the same companies to sit for as MNNIT allahabad...
