Judge your management style, not the feature grid
Both tick every box on the comparison table. The difference is the default path: DingTalk starts at attendance and approvals, Feishu starts at docs and meetings.

Attendance, shift scheduling, leave rules, org-structure changes — DingTalk's granularity fits traditional enterprises better.
Do not ignore migration cost
Moving either way hurts: message history and documents both have to come along. Write down the 'must switch' reasons before you start.
