The practical points most people actually need.
Short answer
It can for some viewers, but it is a harder only-service recommendation than a broader generalist like Netflix.
When it works
When Peacock covers most of your weekly viewing or listening without obvious gaps.

Full answer
The detail behind the short answer.
If the main things you watch sit squarely inside Peacock's strengths, it can work well. If your tastes are broader, it usually feels better as part of a stack.
A service can be perfectly good and still be a poor only-service choice for your household. Peacock works best as a main subscription when its core strengths are exactly the areas you care about most. If it only covers one slice of your routine, it is better treated as part of a stack than as the whole answer.
