It's exactly the same, but the $20 one will almost certainly run out of its daily token alliance if you try to use it for more than an hour or so.

The $20 one doesn't have Opus. (This might or might not matter but it's a difference).

There's also a $100 version that's indeed the same as the $200 one but with less usage.

It does.

For Claude Code?

I think it may be that $20/month gets you access to Opus 4 via https://claude.ai but not in Claude Code.

Oh yes, you’re right, I was thinking about claude.ai

The token allowance is in 5 hour sessions.
