After you guys get yourselves situated with guns you feel comfortable with, jump on Elite and see how you really perform with them in the Weapon Performance tab.
I was surprised to see I had a higher k/d with the MK14 vs the ACR. I run a 1.91 with the MK14 vs the ACR at 1.74, both have similar kills at 1348 and 1384 respectively. CM901 and the G36 perform almost identical for me at a 1.48, making them interchangable with the exception the 901 is better at long range than the G36 but the G36 lays down more bullets in short and medium range.
