Disclaimer: Even after the buffs, I have zero experience or interest in playing a tank. Brutes are something I am much more familiar with.
What metric are we basing this on? While I would have liked to see bruising get a change instead of buffing tank damage so much, I have doubts of any competently built brute losing to a tank in a dps race.
The key is the damage cap and fury. If we are talking about pylon representation, we have to keep in mind that not turning on assault, popping insps or waiting to cap fury are all key factors in a beatdown test. In an actual mission scenario, solo or grouped, with insps and damage buffs being spammed as tons of targets generate fury, I feel like brutes are still second only to scrappers.
