Just to provide another datapoint - tried codex September / October after seeing the glowing reviews here, and it was, all in all, a huge letdown.

It seems to be very efficient context-wise, but at the same time made precise context-management much harder.

Opus 4.5 is quite a magnificent improvement over Sonnet 4.5, in CC, though.

Re tfa - I accidentally discovered the new lsp support 2 days ago on a side project in rust, and it’s working very well.

I was luke-warm about codex when I tried it 2-3 months ago, but just recently tried it again last week, running it against claude code, both of them running against the same todo list to build a docusign-like web service. I was using loops of "Look at the todo list and implement the next set of tasks" for the prompt (my prompt was ~3 sentences, but basically saying that):

    - Codex required around 30 passes on that loop, Claude did it in ~5-7.
    - I thought Codex's was "prettier", but both were functional.
    - I dug into Claude's result in more depth, and had to fix ~5-10 things.
    - Codex I didn't dig into testing quite as deeply, but it seemed to need less fixing.  Still not sure if that is because of a more superficial view.
    - Still a work in progress, have not completed a full document signing workflow in either.

Similar experience and timeline with codex, but tried it last week and it's gotten much better in the interim. Codex with 5.2 does a good job at catching (numerical) bugs that Opus misses. I've been comparing them and there's not a clear winner, GPT 5.2 misses things Opus finds and vice versa. But claude-code is still a much better experience and continues to just keep getting better but codex is following, just a few months behind.

Another anecdote/datapoint. Same experience. It seem to mask a lot of bad model issues by not talking much and overthinking stuff. The experience turns sour the more one works with it.

And yes +1 for opus. Anthropic delivered a winner after fucking up the previous opus 4.1 release.

What are some of the use cases for Claude Code + LSP ? What does LSP support let you do, or do better, that Claude Code couldn't do by itself ?

I checked the codex source code a few months ago and the implementation was very basic compared to opencode
