Which one would each critic pick
| Critic | HappyClaw | NVIDIA NemoClaw | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.0 | NVIDIA NemoClaw — Pick NemoClaw if you already run OpenClaw on Linux and want it boxed; pick plain OpenClaw if you are on a laptop and want the browser and the freedom back. |
| El Crítico | 6.3 | 6.3 | no preference |
| El Profesor | 7.3 | 7.3 | no preference |
| La Inversora | 6.3 | 6.8 | NVIDIA NemoClaw — NVIDIA gives this away and the platform list is the tell: DGX Spark and DGX Station get express installation, which identifies what is actually being sold. |
| La Jefa | 6.3 | 5.3 | HappyClaw — Nothing per seat for sixty people, with run history, delivery receipts, usage statistics and consistent backups in the product, and no directory login anywhere in it. |
| El Hacker | 8.0 | 8.0 | no preference |
