Are debit cards good?

Hey everyone, I am 17 y/o and my parents opened a priority debit card account for me in axis bank today. My dad has a priority salary account so my minimum balance can be zero. I was going through other posts about axis bank priority debit card, and many people were saying that it is basically useless, so I am thinking if this was a right choice or not. I am just going to keep my saved amount in this account and use the money when I am going out.
