| ATM Access | 60,000+ Allpoint + MoneyPass | 43,000+ Allpoint |

Ally Bank Wins
Ally wins on savings APY and the mobile experience. Discover only wins if you'll actually use the 1% debit cashback.
The 4.00% vs 3.90% savings gap costs Discover about $10/yr per $10K, meaningful but not decisive. Ally's savings buckets and budgeting tools genuinely help savers behave better, which usually earns more than the 10bps rate spread. Discover's 1% debit cashback can be worth $360/yr if you actually spend $3,000/mo on debit, but most people use credit cards for daily spending. Ally for most buyers.
