Please answer my two questions separately, thank you! Which of the three cameras, Nikon 6300, Canon 4000 IS and Canon IX US115 HS, is better? Which...

If we divide it by old and new, it is 6300 4000 115. If we divide it by price, it is 6300 4000 115. The functions are the same and the brand influence is also the same. 115 has been discontinued. 6300. There is still room for price reduction. Start with 4000. At that time (reference price is around 1000--1100), it has a large zoom range and is very cost-effective. As a college student, you deserve it. If you don’t understand, ask again.

Thanks for the extra points
