Which one would each critic pick

Criticavante.nvimTabbyPick
El Juez——not enough reviews
El Amigo7.57.0avante.nvim — Pick it if you want Cursor's working style without leaving Neovim; pick CodeCompanion.nvim if you would rather have chat buffers and a workflow engine.
El Crítico6.86.3avante.nvim — It emulates a commercial IDE's interaction model, which makes its design a moving target set by a competitor, and installation needs a native build step.
El Profesor6.86.8no preference
La Inversora6.36.3no preference
La Jefa5.86.0Tabby — 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 Hacker8.88.0avante.nvim — Apache-2.0, and the provider list runs to Ollama and llama.cpp, so the whole loop runs on my hardware with no key, no account and no telemetry.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
