You can also choose axis. Emergency funds shouldn't be in those bank which have the tendency to debit block- kotak/idfc etc
1.Good thing about hdfc is if you maintain enough fd you don't need to maintain sb balance. And icici has best app/nb.
Another good thing about hdfc fd is you can also take mid variant cc through lien fd. Can't with axis. Though you shouldn't get secured cc against Emergency funds.
I can't comment on mobile apps (don't use them). But ICICI's netbanking is nothing to write home about. In fact, in my view, theirs is the worst of the three! In contrast, HDFC's netbanking is obviously designed by smarter people.
