A Brute Rogue also is going to get +Str when using Sneak Attack so that's Str + Cha + Dex for damage which is really, really good.
After maxing two stats, though, you're not going to have much room left for the other one. The third stat probably won't start above 12 or 13. So that's an extra +1 damage at 1st level. At higher levels, the extra bonus might get a bit better, but probably not by much, and not enough to seriously outpace the HP of your enemies.
At any rate, Brutal Scoundrels would probably benefit more from putting those extra points into Con (rather than Cha) over the long run, so the incremental benefit of Sly Flourish for Brutal Scoundrel Rogues is questionable.
Regardless, Sly Flourish remains a solid (but IMO not overpowered or broken) power.
