M6A2 vs M416?

I want to know which one you guys like better. and why you like it more.

The m6a2 has recoil comparable to... probably an MK16 or K2 or SG550... really low, I think it CAN be a 3 hit kill, 4 hit kill usually, good fire rate, good accuracy

The m416 is always a 4 hit kill, sometimes 5. Good fire rate, good accuracy, good recoil, integrated scope

I choose the m416 because any gun with burst capabilities annoys the shit out of me

M416 however CAN be a 3 hit kill. The back is 1.5X damage, so if you shot 3 bullets consecutively in the back, it could be a weak 3 hit kill. Normally it is a medium-strong 4 hit kill. I choose the M416 CQB, great for long range and tapping, low recoil and high accuracy.Plus, i hate the size of the M6a2. Too long and skinny.
