 In conclusion, if you need to ensure subscribers always get the latest value upon subscription, or you have an initial seed value, `BehaviorSubject` is your pick. If you need more historical emissions, consider [`ReplaySubject`](replaysubject.md). And if you don't need any history at all, a simple [`Subject`](subject.md) might be what you're looking for.

 In conclusion, if you want the ability to replay a series of previous emissions to new subscribers, `ReplaySubject` is your go-to. If you only care about the most recent emission (with an initial value), opt for `BehaviorSubject`. And if you want a basic, no-frills broadcasting mechanism where late subscribers miss prior emissions, stick with a plain `Subject`.

 In summary, choose `Subject` for standard multicasting needs. Opt for `BehaviorSubject` when the latest value or seed value is critical, and `ReplaySubject` when you want to ensure a history of values is available for late subscribers.
