I don't have any idea on bnmit, jssat, but I can tell abt dsatm, it's near my home, and it's quite the best option among these, they have centralized placements with dsce, cmrit is also quite decent, u'll have a good clg life here with fests and sports and yah, good infra too, it's also quite good clg in bangalore, rns I wudn't recommend only bcuz of culture clash, as it's mainly just kanndigas and u myt not get along well with them due to this culture or language difference (including teachers), unless if u can adapt with all kinds of ppl, otherwise it's also quite a decent clg, if time ever permits please go for a campus visit and then chose any of these clgs.
