hi shubham,

both are equally beneficial in their own ways. all you have to check is what is your rank in category ranklist (cast wise ranks) and quotas also.

after comparing both of those ranks, using careers360 college predictor you can easily predict the chances of getting a seat in top colleges using your jee rank and wbjee ranks separately and after do that, which ever rank you think can help you fetch a seat in a better college of your choice branch opt for that rank.

hope the information was helpfill

all the best:)
