I don’t know if I am the right person to answer this question but I’ll try to help.
See if you have decided that you wish to join Computer Science then I am sure you will be looking for direct placements after college.
The placement scene is pretty good for CS and IT in JSSATE which is quite similar to Amity and Bennet so that will not be a deciding factor but you should know that Fees in JSSATE is controlled by the UP Government so it is way less than Amity and Bennet. So if you are up for some fewer facilities as compared to Amity then I guess JSSATE will be a better option.
