Cursor is a bit old at this point, the state of the art is Claude Code and imitators (ChatGPT Codex, OpenCube).
Devin is also going very strong, but it's a bit quieter and growing in enterprises (and pretty sure it uses Claude Opus 4.5 and possibly Claude Code itself). In fact Clawdbot/Moltbot/OpenClaw was itself created with devin.
The big difference is the autonomy these models have (Devin more than Claude Codes), Cursor was meant to work in an IDE and that was a huge strength during the 12 months that the models still weren't strong enough to work autonomously, but they are getting to the point where that's becoming a weakness. Models like Devin are getting a slower acceleration but higher top speed advantage. My chips are on Devin
