Which AI IDE should I use under $20/month?

I’ve been trying out a few AI-powered IDEs — Windsurf, Cursor AI, and Trae. I mostly do hobby coding: building small websites, web apps, and Android apps.
I’m looking for something that’s affordable — ideally a fixed plan around $20/month (not pay-as-you-go).
Can anyone recommend which IDE would be the best fit for that kind of usage? Or maybe share your experience with any of these tools?
Thanks!
