I use Rayshud, however I would use IVHud except that it's bugged on 16:10 monitors for people using the sticky launcher. Both of those are good, and Rayshud has options for a more informative scoreboard if you play 6v6 or a normal scoreboard. Both are good so check them out.
I also used to use Star's hud but I dunno if it's updated for the current build.
