KAC Broomhandle and M952 vs. M900

Alright gents I’m here to be persuaded. I currently have a Block 1 CQBR build similar to the first pic with the KAC Broomhandle, a Surefire M952 and a PAQ4B on top. I’ve been looking and pics and videos and I’m kinda digging the M900V/A look on these bad boys. Which one are we selecting for maximum vibes and still being sorta functional??
