SBR's do have more blast, flash, potentially reduced lifespan, and can be more temperamental in function--although the better quality ones run well. An SBR with a suppressor is about the same length as a 16" gun--this is a key fact. An ideal LE rifle is a quality built 11.5-12.5" AR15 run w/can; if that is not available, then a 16" gun makes a lot of sense as a general purpose rifle.
I do have and use a suppressor but I'm finding more and more that I like to leave it off and wear a set of quality electronic ear muffs. They allow me to still hear well but not have the extreme risk of permanent hearing damage (especially indoors) if an SBR is used while allowing me to maximize the maneuverability of the 11.5' SBR.
Of course, this is of little help to my partners if they are inside with me. Our SWAT team uses a set of electronic muffs that plug directly into their radios that accomplish this for the whole team but patrol guys have to supply their own and most do not.
I use the suppressor most frequently when I'm also using night vision.
