Cursor was a great introduction to agentic engineering but I've learned their Claude pricing is largely just batch purchases. Their real moat I think is Composer 2.5 because both their agentic and IDE experiences fall short of Codex and Claude Desktop in my opinion. I think their sales will tell you economically they make the most sense and I would probably agree, but cost isn't everything especially when the spread isn't that wide. At this moment, capability is really king.
These days I'm using Codex and Claude Desktop with Zen when I need to look at code. Codex's real time audio chat feature (not dictation) is also second to none when paired with their agentic flow.
Grok 4.5 is them as well now I guess since they're owned by spacex now. I'd consider grok 4.5 the sonnet and composer the haiku (both capable, fast models).
I actually use grok as my planner and then composer for coding like opusplan in Claude.
