Real-time notifications, WebSockets or Server-Sent Events?

hey everyone, im architecting a new feature that requires real-time notifications to be pushed from the server to multiple clients. im weighing the pros and cons of WebSockets versus Server-Sent Events (SSE). WebSockets seem powerful for full duplex, but SSE feels simpler for unidirectional server push. what are your go-to choices for this kind of use case, and what practical challenges have you run into with either?
