VIT, Vellore is better if you compare it with AKTU, Lucknow and as per Careers360 rating it has got AAAA+ overall (faculty, facility,hostel, placement, cut off trends etc) which says that this is an outstanding college to pursue B.Tech program. Also, to get admission in VIT, you will have to crack VITEEE exam and for AKTU, Lucknow UPSEE is there and it also accepts Jee main rank. So I would suggest you to make VIT your first choice and keep AKTU as a secondary option but also consider your interest and convenience before you make any decision.
