Real-World Test Results (v2.0 - New Engine)

Migrating from jQuery to React

Winner: Draw

Prompt Used:

"Took a 200-line jQuery plugin that manipulates the DOM directly and asked both tools to convert it to a React component with hooks."
Result A:GitHub Copilot tried, but the conversion felt clunky. The component worked, but it still had some jQuery-style thinking in the React code.
Result B:I was impressed by Tabnine's attention to subtle details.

Analysis: From an industry perspective, GitHub Copilot serves professional users who require deep Coding capabilities, particularly around Seamless integration. Tabnine caters to Coding practitioners who value Runs locally (Private). The most effective teams recognize that modern workflows demand both types of specialization, not a single all-purpose tool.

Building a Custom Hook from Scratch

Winner: Tool B

Prompt Used:

"Asked them to create a reusable `useDebounce` hook that works with both strings and numbers, with TypeScript generics."
Result A:GitHub Copilot provided a working solution, but the TypeScript types were a bit loose. Had to tighten them up to avoid runtime errors.
Result B:The artistic nuance Tabnine displayed was impressive.

Analysis: Here is the reality: The difference in output quality stems from GitHub Copilot's deeper integration of Seamless integration principles. Ultimately, the choice depends on whether you value Seamless integration (Tool A) or Runs locally (Private) (Tool B) more.
