Comparing this two institutes are really hard as they are quite similar. But if you want to choose among these then I would say go for Amrita as it has better Curriculum than Satybhama as well as good faculty members. Infrastructurally they are identical or quite same. But curriculum wise I would prefer Amrita more over Satybhama.

** I would recommend you to conduct your own research before taking the decision.

I hope my answer helps. All the very best for your future endeavors!
