Is there any need of map when we can insert & update using List only in contact mailing address?

trigger update_MailingAddress on Contact(before insert,before update) {
set<id> accountIdset=new set<id>();

for(Contact con:trigger.new){
if(con.AccountId!=null){
accountIdset.add(con.AccountId);
}
}
list<account> accList = [select id,billingCity,billingState,billingStreet,billingCountry from Account where id iN : accountIdset];
for(Account acc : accList){
for(contact con :trigger.new)
{
con.MailingCity = acc.billingCity;
con.MailingState = acc.billingState;
con.MailingStreet = acc.billingStreet;
con.MailingCountry = acc.billingCountry;
}
}
}
