We use them interchangeably. Yet a coach, a mentor and a peer do not sit in the same seat, do not answer the same question, and do not produce the same effect. For a leader, the confusion is expensive.
A coach works on you: your posture, your blind spots, the way you decide. They do not necessarily know your business, and that is not their job. They ask questions, they reflect back, they help you get clear. It is valuable, but they remain outside the decision itself. They do not live what you live.
A mentor has walked, before you, a path you are on now. They pass on experience, often from one generation to the next. The relationship is vertical: they know, you learn. It helps when the ground is charted and someone has crossed it. It helps less when no one holds the answer and you must decide in the unknown.
A coach listens to you. A mentor advises you. Neither sits at your level.
A peer stands at exactly your height. The same weight of responsibility, the same orders of magnitude, the same sleepless nights. They do not advise you from above or coach you from outside: they answer you from the same seat. When five peers work through a real decision with you, it is not an expert opinion, it is five readings from people who, this month, carry the same kind of call.
Coaching, mentoring and a peer circle are not at odds: they answer different needs. But when the question is "how do I decide, alone, in the unknown", it is the peer, not the coach or the mentor, who changes the game.

A circle of five peers, composed for you. Not a coach, not a mentor.
