Some of those listed were paid annually. So regardless of if interest is calculated daily, if you withdraw the money perhaps to move to another provider you've got a long wait for the interest. If it's an account that matures annually, then it's worth checking if you'll get anything if withdrawing early or if there are any penalties. As not all them are true easy access accounts. Paragon for example which was listed in the link only allows 2 withdrawals, so isn't a true instant or easy access.
Typically, for an easy access account you're going to want the interest calculated and paid as frequently as possibly for maximum flexibility.
