Claude Max 20x vs Google AI Ultra 20x: choose Claude Max 20x if agent quality is the point. Both cost the same $200/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score. The two plans are compared on what a week of real coding tasks fits, not on a feature list.Measured
Our verdict
Choose Claude Max 20x if agent quality is the point. Opus 5.5 and Fable handle planning and hard work that Google has no top-tier model for right now.
Choose Google AI Ultra 20x only for very heavy use across Google products. More Gemini does not fix Antigravity or add a stronger model.
$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.
How far it goes: we have not measured this plan
Same models and harness as Claude Max 5x with more allowance - the Max 5x scorecards are the closest evidence.
$200 buys the highest Gemini usage and the largest Google bundle. It does not improve Antigravity or the available models. Buy this only if the lower Google plans cannot provide enough usage.
Pros
The highest Gemini usage
The largest Google services bundle
Cons
The same rough Antigravity agent
The same models as the $20 plan
Best for People who need maximum Gemini usage and will use the Google bundle.
How far it goes: we have not measured this plan
Same Antigravity CLI as AI Pro with a far bigger allowance - the AI Pro scorecards are the closest evidence.
