It was barely better than Cursor and they got shafted by Anthropic because of the takeover announcement so nobody really used it anymore because let's face it - Claude Sonnet is just the best coding model. Design-wise the chat panel and autocomplete integration was a bit nicer than in Cursor but not by much. Subscription for Windsurf was/is also 5$ cheaper.
i don't think it was better than or comparable to cursor at all. except for the month prior to the OpenAI Acquisition news where some minor influencers on X were calling it better.
