5x Max is the plan I use because the Pro plan limits out so quickly. I don't use Claude full-time, but I do need Claude Code, and I do prefer to use Opus for everything because it's focused and less chatty.
You are clearly overpaying for your groceries. I can cook for a week from the difference.
If there wasn't a significant difference, they would offer 2x Max, the demand is there. But they don't. Clearly, their strategy works on fanboys like you.
