The “Try Before You Buy” Strategy

Most tools have free tiers. Here’s an evaluation path:

Week 1-2: Try the Free Tiers

Copilot (if student) or Codeium
Cursor Free (50 premium prompts)
Windsurf Free (limited Cascade)

Week 3-4: Evaluate Your Needs

Did inline completions help most? → Copilot
Did multi-file editing matter? → Cursor
Did context memory help? → Windsurf

Month 2: Commit

Pick the tool that matched your workflow. Cancel the rest.

What I Actually Use (Real-World)

Most power users end up with a combination:

Use Case	Tool
Daily coding	Cursor Pro
Complex reasoning	Claude Pro
JetBrains projects	Copilot
Quick prototypes	Windsurf

Monthly cost: $20-40 depending on combo.

Bottom Line

Students: Get Copilot free
Budget: Copilot ($10) does the job
Power users: Cursor ($20) is worth it
Terminal fans: Claude Code ($20)
Long projects: Windsurf ($15)

Don’t overthink it. Start with Copilot ($10). Upgrade to Cursor when you hit limitations. You can always switch—they all work with similar codebases.
