Account Features Comparison
Ally Bank is a full-service online bank. It offers checking accounts, savings, money market accounts, CDs, auto loans, and the savings "buckets" feature that lets you organize up to 10 savings goals within one account. Ally has ATM access through its checking account and reimburses up to $10/month in out-of-network fees. Best choice if you want to consolidate all banking at one institution.
Marcus by Goldman Sachs is a savings and CD specialist — no checking account, no ATM access, no debit card. Pure savings and fixed-term CDs. The simplicity is a feature for savers who don't want to be tempted to spend, but it means Marcus must be paired with another bank for everyday spending. The app is clean (4.9/5 App Store).
Discover Bank bridges the gap — it offers savings accounts, checking accounts with 1% cash back, money market accounts, CDs, and personal loans. Discover's checking account is competitive with Ally's, and the savings rate is higher than both rivals. No monthly fees anywhere. Discover's ATM network is one of the largest among online banks.
FDIC Insurance
All three are FDIC insured up to $250,000 per depositor per ownership category. This is the regulatory baseline for all U.S. bank accounts — there's no meaningful difference in safety between these three institutions.

How Rate Changes Affect Ally, Marcus, and Discover Savings
All three accounts hold variable-rate savings products — rates change when the Federal Reserve adjusts the federal funds rate. Historically, online banks like Ally, Marcus, and Discover pass rate increases and decreases to savings accounts within 1–4 weeks of Fed action. The rate differential between these three is typically 0.05–0.25% — meaningful on large balances, negligible on small ones. On $50,000, a 0.20% rate difference is $100/year. The primary selection factor should be the institution you trust and whose interface you'll actually use, since rate differentials are small and change frequently. Set a calendar reminder to compare rates quarterly and move funds if one institution falls more than 0.30% below competitors — but don't obsessively rate-chase between accounts for small differentials.
