GR-3 · Best for

Senior living communities: companionship, fall monitoring, medication reminders via natural voice.

Adam-U · Best for

Vision-language-action (VLA) policy pretraining in simulation-to-real pipelines (teleop → imitation learning → autonomous deployment on fleet robots)

Final judgment

If immediate deployment is the priority, choose GR-3. If the goal is to be ready when Adam-U's capabilities mature, track it.
