I switched to Anthropic briefly to try out Code, it was great (having never tried such a product) and better than their chat bot which found prettier and nicer to talk to but far more often wrong.

Then shortly after Codex was released which made that more accessible and instantly preferred that compared to Code since much more generous allotments for $20 plan. Claude constantly kept hitting. And Code actually had a more robust UI and was more accurate when doing the same project side by side vs Claude Code.

But imagine many haven't tried Codex recently since all we hear about is Claude Code. So while they may have momentum, at least for me with no stake in the game, Codex finding far better, but I suppose that could all change again on a whim.
