I'd suggest to just give it a shot and notice the difference, it's night and day.
I couldn't get cursor agent to do useful stuff for me - might be because I don't do TS or Python - and Claude Code was a big productivity boost almost from day one. You just tell it to do stuff, and it just... does it. At like the level of a college student.
I'm writing TS and I was not very happy with Cursor - I expected more coming from using Cline + Sonnet in VS Code. I tried the composer or how do they call it, and the results were mediocre. After few hours of struggling I gave up and returned to Cline. Now with Claude Code I got much more value right from the start. I don't know, maybe I was "holding it wrong".
I am using the Cursor agent mode, which can run in auto mode with, let's say, 50 consecutive tool calls, along with editing and other tasks. It can operate autonomously for 30 minutes and complete a given task. I haven't tried Claude Code yet, but I'm curious—what exactly does Claude Code do differently compared to the Cursor agent?
Is the improvement in diff quality solely because Cursor limits the context size, or are there other factors involved?
