I use PHP/Symfony/Websockets for a real time web app.

I have been looking over at SSE/Mercure for a while, as Symfony recomends it for Server->Client traffic. https://symfony.com/doc/current/mercure.html

However I am yet to see a reason to swap out my currently working websocket implementation other than SSE is the new shiny thing.

Can anybody tell me any other benefits that I may get from making this switch?
