Our verdict
Claude Max 20x is the stronger product, but it costs ten times as much as ChatGPT Plus. Most individual users do not need its parallel-agent headroom.
At $20, choose Claude Pro. Opus 5.5 takes the hard work and Sonnet 5.5 the small tasks. If you outgrow Pro, Claude Max 5x is the sensible next step.
$20 gets you Codex with every OpenAI model, including Astra. Luna handles high-volume small tasks at a fraction of the quota. OpenAI's extra resets are getting fewer and fewer, so don't rely on them lasting much longer.
Pros
Every OpenAI model, including Astra
Luna is cheap on quota
Generous allowance while the extra resets last
Cons
Opus 5.5 is stronger at the same price
Astra can drain the whole 5-hour window in one prompt
The current allowance depends on temporary extra resets
Best for People who want Luna for high-volume small tasks.
How far it goes: at least 15 times a week, and more than 100 for the cheapest model
Our whole real-world issues and spec planning pass runs at least 15 times a week, and more than 100 for the cheapest model on this plan, depending on which model you run.
That works out at about under 5c to 28c of the subscription per run, at the list price.
Measured on this plan, at <1% to 6%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
$200 is the largest Claude allowance, with Opus 5.5 and Fable through Claude Code, the best CLI agent. That is room for many agents running all day. Opus 5.5 does most of the work. Fable is there for the hardest planning. Buy it only if the Max 5x limit is blocking your work.
Pros
The largest Claude allowance
Many Opus 5.5 agents all day
Sonnet 5.5 for smaller things and simple tasks
Fable for the hardest planning
Cons
Max 5x covers most days for $100 less
Best for People who keep hitting the Max 5x limit. Start on a cheaper plan first.
