Do not index
Everyone's writing claude code vs cursor posts with benchmarks and pricing tables. I don't care about any of that. I care about what happened to me yesterday. So let me just tell you.
The bug
I had a bug. A value was coming out as undefined. Simple prop, shouldn't be undefined, was undefined. You know how it is.
I use both claude code and cursor but normally I just go with claude. So I did the same thing I always do. Told it to find out why this prop is becoming undefined.
It reads a few files. Comes back and tells me it's because of this other piece of code. I look at it and honestly it looks completely unrelated to what I asked. But claude sounded so sure, so I approved it anyway.
Only to find out later, I was right. The change it made had literally nothing to do with my bug.
An hour. Gone.
I kept trying everything it suggested for an hour. An hour! New theory, try it, still undefined. Another theory, try it, still undefined. At some point I just gave up on claude and opened cursor.
Cause it has the right tool for this. Debug mode.
I've been using cursor for two years now. I thought claude is the more advanced tool, top of the line, it must have something like this too. Turns out it doesn't. Which is honestly stupid for a tool this popular.
What cursor did in 2 tries
If you've used cursor's debug mode before you already know what I'm talking about.
It adds logs on its own and just asks you to reproduce the bug. In the browser. That's it. Any browser!
Think about how advanced that actually is. It's not guessing from reading code, it's watching what your code is actually doing while you break it in front of it.
I turned on debug mode, explained the problem, and it told me: restart the server -> go to browser -> reproduce the bug.
I did that. It read what happened. Fixed it in 2 tries.
TWO. After an hour of nothing from claude.
Wait what
This is the part that actually got me. I use claude code all the time. I genuinely thought it was the smartest, most advanced tool out there. So when I saw what cursor's debug mode could do, I just assumed claude must have something similar too.
I literally asked claude to do the same thing. Add logs, let me reproduce it, read what happens. It said it can't.
That's when it hit me. Cursor's built in tools straight up make it more powerful than the CLI ones for stuff like this. Not smarter. Not better model. Just... it has the tool for the job and claude doesn't.
So what do I actually think now
I'm not dropping claude code. For big stuff, moving fast across a bunch of files, exploring a codebase I don't know well, it's still what I reach for first.
But for a real bug, one where the code looks fine but something is still broken, I'm not wasting an hour with claude guessing anymore. I'm going straight to cursor's debug mode.
The whole thing kind of humbled me honestly. I assumed the "smarter" sounding tool would obviously have every good feature the other one has. It doesn't work like that. Sometimes the tool you've had for two years and stopped thinking about has the one thing that actually saves you.
