Colleges in Australia

First of all, I must tell you that any college of AKTU is not at all satisfactory.
Amity being a big brand has maintained its reputation over the years and has a variety of programmes to offer to its students and is a good college. Again, don't get your hopes too high about Amity when I say it's a good college, as when we consider Amity in comparison with other colleges present all around the country it stands nowhere on the list of the top colleges in India.
Being a big brand, Amity has managed to attract a number of companies which is why placements at Amity are certainly a lot better than placements at Galgotias University-Noida.
Amity is big, big enough that you would never be able to cover the whole campus on foot in one day. At the same time, Galgotias University has also got a great infrastructure but is still lacking in front of its competitor.
Although academics are slightly better at Galgotias University, you still get a better placement at Amity because of its brand name and reputation.
I hope you make the right choice. Good luck!
