I've picked up the MP-7 and much prefer it over any of the engineer shotguns.... As for the F2000 I only use it when i'm USMC for the full auto option. But AK's are all you really need for assault. And I never touch the support kit really.
So go MP-7 or F2000. Leaning towards MP-7 since you have the most time in that.
