I'm not what I'd call a heavy user, but I've also mainly been using Copilot in VS Code on the basic sub.

You do get Opus 4.6, and it's really affordable. I usually go over my limits, but I'm yet to spend more than 5 USD on the surcharges.

Not seen a reason to switch, but YMMV depending on what you're doing and how you work.

Longtime happy Copilot user here. It's true.

The pricing is so good that it's the only way I do agentic coding now. I've never spent more than $40 in a month on Opus, and I give it large specs to work on. I usually spend $20 or so.

It is true, it's the official pricing of GitHub Copilot.
