M4A1 Xmas vs. other rifles

Hello guys, it's me Pexii.
When the m4a1-xmas appeared in my inventory, I decided to use it before esl to warm up.
That was the worst thing I ever did in CF. On port (usually mid and long-range) I killed 14 and died 3 times, BUT from the 14 kills only 4 were headshot. I thought it's kinda unusual, so I decided to make a thread how good is the m4a1-xmas compared to other guns.

All stats are TD Ship 150 kills, 8v8. (PUB, not competitive or scrim.)

M4A1-Xmas : 37 kills, 12 headshots. It's a bit more than 30% hsrate. 13 Deaths.
Reg. M4A1: 48 kills, 37 headshots. It's 77% hsrate. 11 Deaths.
M16A2 : 45 kills, 33 headshots. It's 73% hsrate. 9 Deaths.
Normal M16: 41 kills, 28 headshots. It's 58% hsrate. 14 Deaths.

So personally, I think M4A1-Xmas got a pretty nice lookout, but for me it's unaccurate.
If I make better rate with reg. M16, I think it's not the best gun. Still good, that z8 gifted these sexy guns for 7 days. Ty.
Maybe, it's just my mistake I can't use it.

Thanks for checking the thread,
