an-94 scar (love its iron sights) ballista (most balanced sniper rifle, en mi opinion) 870 msmc
runners up: all the pistols except the executioner
Really, you think the ballista is the best sniper rifle? I just got diamond snipers last night, and it's my least favorite...what makes it the most balanced in your opinion? The DSR gets more reliable OHKs, the XPR is just as reliable in terms of OHK, plus it's semi auto...the SVU is the only one that doesn't OHK as reliably, but it's semi auto and has virtually no recoil to make up for it...
The only thing the ballista has going for it is iron sights, and I'm not that impressed with those. I'd much rather just use the KSG with reflex.
