I use CC/Codex/Cursor.

CC is mostly my default for large tasks / features (ex. Plan > execute plan ) Biggest gripe with Claude Code is that it is painfully slow relative to the other two.

Cursor for small stuff like bug fixes since it has a lot of models to choose from. I love the review/ diff / checkpoint features. It's planning feature is on par with CC. I'd probably use Cursor as primary driver if it had better cost efficiency. Next version or two of Composer may fill that gap in cost/quality/speed.

Codex isn't allowed at my work, but I use it for personal projects. It has the best balance of quality / cost / speed even if it's planner is poor and quite frankly the codex harness needs to catch up with the other two.

CC for quality / cost. Cursor for quality / speed. Codex for balance of the 3.
