Should, ought to, and had better all give advice, but each has its own grammar quirks and its own level of urgency.
What you'll learn
Should, ought to, and had better all give advice, but they sit at different points on a scale from mild suggestion to urgent warning.
Should and ought to mean almost the same thing, but ought to keeps its to in every form — unlike should, which never takes to. Ought to is also less common in negatives and questions, where should is far more natural.
Had better is stronger than should or ought to — it usually implies something bad will happen if the advice isn't followed. Despite looking like a past tense (had), it's about the present or near future, not the past.
Unlike should, ought always keeps to before the base verb.
Had better is followed directly by the base verb, with no to.
The negative of had better is formed with not right after better, not with wouldn't.
"We should leave soon, the traffic will be bad."
"You're right. You'd better grab your coat too, it's cold out."
"Good call. Ought we to call ahead and let them know?"
"Probably — better safe than sorry."
