real-time chat, dont you hate when it lags?

hey everyone im working on a project that needs real-time chat functionality im weighing the pros and cons of using websockets versus server-sent events sse websockets seem powerful for bi-directional communication but sse feels simpler for one-way server pushes for a typical chat app where users send messages and receive them whats your experience when did you choose one over the other and what were the deciding factors are there specific performance or complexity trade-offs to consider
