Same experience here. I started our devoutly using Claude but ran into some many limits that I switched back to ChatGPT and it's been night and day. I haven't even really been able to play with the Opus model on my Pro plan because it devours usage and then blocks me for X hours until it resets, costing me a work day. OpenAI has never done that to me. In fact, Codex just churned away for 2 hours on a task and I'm still using it without hitting a limit. I used to love using Claude but the limits are too prohibitive.
