Build Source Engine From Github vs Source engine + Debugging Symbols through Epic Games

So me and my team are building a multiplayer game, we will need to host a dedicated server that can host up to 15 players per session (We will need dozens if not hundreds of open servers/lobbies at the same time).

My question is, since we’re gonna have multiplayer in this game, do we need to build from the source engine in Github or would the installing UE5 + Source Engine + Debugging Symbols options through the Epic Games Launcher be enough?

We have both, devs writting code in C++ and BPs.
