The field
Each kit in its own words.

Before you pick
Answer these before you open a file.
Each answer rules out part of the table, this file included.

Platform
A phone or a browser?
For a browser, take a web kit and stop comparing. For one phone platform, its official kit is the baseline. For both from one file, you need both conventions in it.

Brand
Will the brand change?
It usually does. Count the places you edit when it changes; if the answer is more than one, the file will drift.

Handoff
Values or a document?
A specification gets retyped, and every retyped value is a place design and build can disagree. Tokens exported to SwiftUI, Compose, Flutter and CSS reach the build as they are.
Fit
Where this file is the wrong buy.
Buy something else
When a different file is the better answer.
You are building for the web. A web system will serve you better and cost you less time.
You want a pile of screens to copy from rather than a system to build on.
Your team already runs a mature design system of its own.
Buy this one
When the architecture pays for itself.
You are building for a phone.
iOS, Android or both. Everything in the file was drawn at phone widths.The brand will change.
Two token levels keep the change to one edit.Your developer wants the values.
Tokens arrive as SwiftUI, Compose, Flutter and CSS, so nobody retypes a hex into a stylesheet.Dark mode ships on day one.
Every component carries both modes through the same semantic tokens.
Open the read-only Figma preview before you decide either way. It is the whole file, which is the one part of this a comparison page cannot show you.
