I'm not sure I understand the phrase "you'd better". Is it more a suggestion than an order? I have a context where I'm thinking of using it:

You'd better stop what you're doing, Paul. It's over. I've called the police. They're on their way.

Does it seem natural to use here as an order or maybe even a threat or is it too weak for the context?


It could be eg advice ,an order, a suggestion . . . .

It depends on the context. For rexamlpe, has Paul got a gun?
