I used Cursor for the total of one day (paid for a year subscription), discovered Claude Code later that day and havent opened Cursor since.

Note, later I started using Codex and now Codex is my daily driver, Claude Code for problems where Codex fails (not many), and again Cursor is never used.

They were the first mover but Codex (in my opinion) blows Cursor up into 1000 tiny pieces. It's just so, so much better.
