I have not tried the Gemini CLI in a few months but when I did it was a shit show.
Google makes it very hard to use their shit and it was full of bugs.
Anthropic's current run is based entirely around Claude Code in this space and the last time I used the gemeini-cli it wouldnt give me access to the latest models and I was paying them for the privilege
Google trashed the Gemini CLI client and replaced it with agy (antigravity), which is written in go and is much nicer.
