CU is relatively new, so I would be careful before hedging my bets there.
When it come to LPU and Amity, you should consider a few factors. If you live near LPU or relatively near compared to Amity University Noida, I don't see any point in going to Amity. Similarly if you live in the Delhi-NCR region, I find no reason for you to go to LPU. Both colleges are very similar in terms of quality of academics and placement. Thus, between LPU, Amity and CU, I'd advice you to make a call between LPU and Amity based on whichever is closer to your home. You can also refer to the article in the link below.
