Right now in the current meta, I would rather take a squad of low BR's into battle than high BR's. Currently high BR's try to farm certs, and maintain stats like a high KDR. This method of fighting leads to not taking risks, staying so far away from the fight that enemies can respawn and get back into the fight before it matters that you killed them, and running when you dont have a decided advantage. Low BR players bumrush the point, spray, die, respawn, repeat. And this actually is an effective tactic for capturing bases. We have near instant respawn timers, abusing that and dying in glorious battle is more effective than farming and maintaining your KDR, for the stated goal of the game. Which is conquering bases and continents. TL;DR low KDR players are more effective at capturing bases.
