real time updates, websockets vs server sent events vs polling

Hey everyone, I'm working on a project where we need to push real-time updates to clients. We're trying to figure out the best way to do it, looking at WebSockets, Server-Sent Events (SSE), and just regular old polling. Each one seems to have its pros and cons, you know, with how complicated it is to set up, how well it performs, and if browsers actually support it. What have you guys found? When did one of these really stand out as the way to go for real-time data? Any tricky bits or tips I should know about?
