Do these tools actually make you faster or is it just hype?

Depends on what you're doing. For boilerplate CRUD APIs and React components? Yeah, maybe 30-50% faster. For anything complex? You're on your own, buddy. For complex architecture decisions or debugging race conditions? They're useless. I save about 4-6 hours per month with Cursor when it's not crashing. With Copilot Enterprise, maybe 2-3 hours but it's more consistent. Your mileage may vary.

Why does Cursor crash so damn much?

Memory leaks and poor resource management. Large projects (100k+ lines) kill it. I've had Cursor consume 16GB RAM and freeze my entire MacBook Pro M2. The indexing process seems to have memory issues, especially with monorepos. Got this exact error: `Error: spawn ENOMEM` when it tried to index our 150k line TypeScript project. Tons of users are reporting similar issues on their forums.

Is GitHub Copilot Enterprise really $58/month or is that marketing BS?

It's real. [$39/month for Copilot Enterprise + $19/month for GitHub Enterprise Cloud](https://docs.github.com/en/copilot/get-started/plans). Sales will tell you "$39" and conveniently forget the Enterprise Cloud requirement. For a 10-person team, you're looking at $6,960/year vs Cursor's $4,800/year.

Which one breaks less often?

Copilot Enterprise by a mile. I've had zero crashes in 6 months. Cursor crashes 1-2 times per week, usually during demos or important work. Memory usage is the killer - Cursor will slowly eat your RAM until your system chokes.

Can I actually switch from VS Code to Cursor without losing my mind?

If you're not heavily customized, yeah. If you have 50+ extensions and custom keybindings, prepare for pain. Cursor is VS Code underneath, but some extensions break. GitLens acts weird, some themes don't work right, and you'll spend 3-4 hours minimum reconfiguring everything. I learned this the hard way after trying to replicate my exact VS Code setup. Spent a whole weekend fighting with Vim keybindings.

Is the AI actually better in Cursor or is it placebo effect?

Cursor's Tab autocomplete is genuinely better - like, significantly better. It predicts entire functions correctly maybe 70% of the time vs Copilot's 40%. But Cursor's chat AI isn't dramatically different from Copilot Enterprise's. Both have access to similar model families, just different implementations.

What happens when your internet dies?

You're fucked with both tools. Neither works offline. You'll be coding like it's 2015 until your connection comes back. At least with Copilot Enterprise, VS Code still functions normally. With Cursor, you're stuck with a broken AI IDE.

Do these tools actually understand my codebase or just pretend to?

Cursor actually indexes your entire project and understands relationships between files. Ask it to "add authentication to this API" and it'll modify routes, middleware, and database files correctly. Copilot Enterprise has context awareness but can't do complex multi-file operations.

Which one is easier to get approved by IT/procurement?

GitHub Copilot Enterprise, hands down. Microsoft backing, enterprise contracts, IP indemnity protection. Cursor is a 3-year-old startup that IT departments don't trust yet. I've seen procurement teams kill Cursor purchases over liability concerns.

How long does it take to actually see productivity gains?

- **Cursor**: 2-3 days if you adapt to the Agent mode workflow. Game-changing for refactoring tasks. - **Copilot Enterprise**: Immediate for simple autocomplete, but modest gains. You'll notice it, won't blow your mind.

What's the most annoying thing about each tool?

- **Cursor**: Random freezes during important work. Nothing worse than losing 30 minutes of context because Cursor decided to die. - **Copilot Enterprise**: Mediocre suggestions. It works, but you'll think "meh" more often than "wow."

Can I use my own API keys instead of paying their markup?

Cursor lets you use your own OpenAI/Anthropic keys for some features, but not their custom Tab model or Agent mode. Copilot Enterprise doesn't support external API keys at all - you're locked into their pricing.

Which one handles large/legacy codebases better?

Depends on "large." Cursor is amazing at understanding complex codebases under 50k lines. Above that, it starts choking. Copilot Enterprise handles any size project consistently, but with less deep understanding.

Should I wait for the next version or just pick one now?

Pick now if you need productivity gains. Both tools are evolving rapidly. Translation: they're fixing the bugs you'll discover for them. Cursor is adding stability fixes, Copilot is improving AI quality. Waiting is just leaving money on the table.

What's the real learning curve like?

- **Cursor**: 1-2 weeks to master Agent mode and Tab workflow. Worth it if you do lots of refactoring. - **Copilot Enterprise**: 2-3 days to learn the keyboard shortcuts. It's just better autocomplete.
