We used the MP5's all day, every day, in all sorts of missions and frankly I don't care to label it one or the other. It's just an utterly reliable, accurate and ergonomically-sound 9mm SMG.
As for the Blackout, it's not as quiet subsonic as the MP5-SD. Burns three times the powder as a 9mm for no more killing power. The heavy 30cal bullets currently used in factory ammo are match bullets designed for higher velocities. They act like monoliths on hitting flesh. Every animal I have taken with a subsonic Blackout is a through-and-through (wasted energy). But, the Blackout does permit supersonic rounds and that is a big advantage in a PDW. If SIG makes a .223 version that would be worth a look.
The 300 BLM (7.62x45) seems to like shorter barrels where the 5.56x45 really needs a barrel longer than 14".
That is where the 300 BLK stands out is its love of shorter barrels.
