Our verdict
Choose Google AI Ultra 20x. It costs about the same. The Google bundle has value even if you never code.
Kimi Vivace does strong visual design, but it drains limits too fast to recommend.
$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.
$199 gives K3 ten times the agent credits of Allegretto. The usage limit still runs out too quickly. K3 has regressed in our use since release. More credits do not make it worth buying.
Pros
The largest Kimi credit pool
Good visual design
Cons
The usage limit drains too quickly
K3 has regressed since release
Best for Nobody.
