Surface vs model
Both are IDEs with an agent. Cursor’s Composer is the more documented English workflow. Trae’s pitch is native Chinese UX plus model switching (Claude / DeepSeek / Doubao) without starting from a $20 seat.
Who should not switch
If your team already standardized on Cursor rules, MCP, and Composer diffs, switching to Trae is a process cost. If you are starting today in a Chinese-language team, Trae plus DeepSeek-V4-Pro is the cheaper experiment.
