> The real benefit is time of transfer. ACH is infuriatingly slow. If you'd like a payroll run to arrive in employee accounts on a Friday, it must be initiated almost a week prior.

Ya, this isn't true. the ACH spec does say 3 business days, but 2 of those days are for redundancy. In all normal cases a transaction submitted today can and will post tomorrow. Your bank may not allow this for individual transactions, but it isn't because ACH can't accommodate it.
