I chose SBI when I had to create a govt bank account too. Had some trouble because I had digital bank account with them, which was deactivated and it took them several days (& having to visit branch daily, visiting different counters and the dead-like manager) to reactivate that and convert it to regular savings account.
Overall, have not had much issues with their netbanking or their app once the account was created. Only UPI server being down at times, but it is my secondary account, so it is fine.
