The luck in the chamber roll plus the high impact acts as an extended range of sorts, allowing you to 3 shot from long distance that the Palindrome cant. "Ghost bullets" seem less likely to happen on a slower handcannon. Also I like the high burst damage to finish people off if a fusion -blam!-s up and doesnt fully kill. Ultimately up to personal taste. Palindrome is arguably better but oh whale. I like my two taps haha
