I'm pretty sure we are in an apple vs android situation, where you give lifetime apple users an android phone, and after a day they report that android is horrid. In reality, they just aren't used to how stuff is done on android.
I think many devs are just in tune with the "nature" of Claude, and run aground easier when trying to use gemini or Chatgpt. This also explains why we get these perplexing mixed signals from different devs.
There are some clear objective signals that aren’t just user preference. I shelled out the $250 for Gemini’s top tier and am profoundly disappointed. I had forgotten that loops were still a thing. I’ve hit this multiple times in Gemini CLI, and in different projects. It gets stuck in a loop (as in the exact same, usually nonsense, message over and over) and the automated loop detection stops the whole operation. It also stops in the middle of an operation very frequently. I don’t hit either of these in Claude Code or Codex.
There certainly is some user preference, but the deal breakers are flat out shortcomings that other tools solved (in AI terms) long ago. I haven’t dealt with agent loops since March with any other tool.
Agreed. Been using Claude Code daily for the past year and Codex as a fall back when Claude gets stuck. Codex has two problems: it Windows support sucks and it's way to "mission driven" vs the collaborative Claude. Gemini CLI falls somewhere in the middle, has some seriously cool features (Ctrl+X to edit prompt in notepad) and it's web research capability is actually good.
I'm constantly floored with how well claude-cli works and gemini-cli stumbled on something simple the first time I used it and Gemini's 3 Pro release availability was just bad.
I too am curious. My daily driver has been Claude Code CLI since April. I just started using Codex CLI and there are lot of gaps--the most annoying being permissions don't seem to stick. I am so used to plan mode in Claude Code CLI and really miss that in Codex.
The model needs to be trained to use the harness. Sonnet 4.5 and gpt-5.1-codex-max are "weaker" models in abstract, but you can get much more mileage out of them due to post-training.
Ah, Gemini is the model and Google Vertex AI is like AWS Bedrock, it's the Google service actually serving Gemini. I wonder if Gemini can be used from OpenCode when made available through a Google Workspace subscription...

Good. I'd rather use a tool designed with focus on modern standards than something that has to keep supporting ancient ones every time they roll an update.
YMMV I guess but it's my goto tool; fast and reliable results at least for my use cases

have you received your money's worth in other products?

Claude had the same feature for editing the prompt in $EDITOR
Codex prompt editing sucks

Well Opencode also completely replaced its TUI a few weeks ago too.
BTW Gemini 3 via Copilot doesn't currently work in Opencode: https://github.com/sst/opencode/issues/4468
Copilot on Opencode is not good. It’s all over the place which is a shame because Copilot is one of the best values.
what happened with Codex? Did they rebuild it?

Codex CLI switched from a typescript implementation to a Rust based one.

What's wrong with any terminal? Are those performance gains that important when handling a TUI? :-(
Edit:
Also, I don't see Gemini listed here:
https://opencode.ai/docs/providers/
Only Google Vertex AI (?): https://opencode.ai/docs/providers/#google-vertex-ai

It's silly of them to say you need a "modern terminal emulator", it's wrong and drives people away. I'm using xfce4-terminal.
Gemini 3 via any provider except Copilot should work in Opencode.
