HUDs - The current system?

What’s the current standard for HUDs? I’ve been watching some tutorials that use the HUD actor class and you add Widgets to it, but apparently that’s outdated and just legacy code?

I need it for each client to have their own HUD, and it will display some stats and stuff from the GameMode. I looked at this tutorial but the comments (screen cap attached) were saying that doing it that way is not suitable for multiplayer because it overlays everbody’s UI on top of everyone else’s:

Thanks for the assistance.
