Hi aspirant,
To be very honest, the placement records and opportunities at Vellore Institute of technology is much better than the north eastern NIT'S excluding Guwahati and IIIT'S. Though rankings are not a clear measure the colleges mentioned by you are still growing and need few more years to be at a par level. In general the nit colleges which were established in 2005 and earlier including new likes of Trichy, Wrangal, Silchar have been performing well and can be chosen ahead of VIT. While in terms of IIIT'S Hyderabad, Bengaluru, Delhi, Allahabad, Indore are quite ahead.
In case these options are not available to you based upon your rank, stick with Vit and it will not let you down.
Hope it helps!!
