Ally Bank verdict
Ally is the best-in-class for users who want a full banking relationship rather than just a high yield. The Buckets and Boosters features for goal-based savings are genuinely useful and not gimmicks. APY is competitive but not the highest on this list — pay this small premium for the ecosystem.
