Peacock makes the strongest early shortlist for people who already know they want NBC, Bravo, selected sports, or a lower-cost complement to a broader streaming stack. Those are the users most likely to feel the service's strengths quickly rather than having to talk themselves into them.
The opposite test matters just as much. Peacock is usually a weaker first choice for households trying to replace every other service with a single massive catalogue. That does not make it bad; it just means its strongest arguments are aimed somewhere else.
