Pi comes out ahead on approval (84 vs 29 overall, 80 vs 25 in the last 90 days) and on customization, with 150 positive mentions against 4 negative. Gemini CLI's record is dominated by reliability complaints (7 positive, 55 negative) and UX complaints (7 positive, 28 negative), and users name Claude Code, Codex, and Antigravity as replacements. Pi also has more evidence behind it: 423 opinions from 335 authors, against 211 from 175 for Gemini CLI.
