By Marcus Cole10 min readUpdated September 30, 2026
Chime, Ally, and Marcus by Goldman Sachs all show up on 'best online banks' lists for millennials — but they're aimed at different goals. Nobody taught us this. Let me fix that.
Chime in plain language

Ally in plain language

Marcus in plain language
Marcus by Goldman Sachs focuses on savings products like high-yield savings and certificates of deposit, plus personal loans. It tends to fit savers who want to park cash with a well-known brand.
