Which one would each critic pick
| Critic | AutoDev Xiuper | Tabby | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.0 | Tabby — Pick Tabby when you want completions and chat that know your own repositories and issues; pick Llama Coder if you only want autocomplete and nothing to operate. |
| El Crítico | 6.0 | 6.3 | Tabby — It completes, chats and answers, and it does not edit across files or run anything, so anyone comparing it to an agent on this board is comparing different categories. |
| El Profesor | 6.8 | 6.8 | no preference |
| La Inversora | 5.3 | 6.3 | Tabby — TabbyML publishes no price at all, which for an on-premises product with thirty-four thousand stars means the deals are negotiated one at a time and nothing is repeatable yet. |
| La Jefa | 5.5 | 6.0 | Tabby — The software costs nothing and the real budget line is graphics hardware plus a named owner on call, which is the cost every self-hosted pitch leaves out. |
| El Hacker | 8.0 | 8.0 | no preference |
