The chat UX is definitely better than Cursor. It less janky and I like that it wait until generation is done before asking you if you want to apply the suggested the changes instead of loading them into your file right after like cursor does. Also you can apply at cursor which is nice for snippets.

The Builder tool is probably the best feature of Trae. It builds React UIs better than any tool even v0 which is built for building React UIs. It very good at recreating UI from image even better than using the model directly which I'm not too sure how...

Code completion is probably closer to copilot than cursor so it depends on how hardcore you like your AI code completion. So Cursor might be better especially for repetitive refactoring.

The overall design and feel of Trae is better the VS Code and Cursor, but I'm a big fan of JetBrains and it feel a lot like a JetBrains IDE.

DeepSeek is absolutely the leader in terms of cost value for high performance AI models.

US firms might have the lead in terms of absolute best performance, true. But their prices are 10-20x more for a product that is marginally better at most. When it comes to coding DeepSeek V3 is very close to Claude 3.5 Sonnet and exceeds GPT-4o.
